Written by Cast Member

Michael Norell's writing credit on fourth-season Emergency! episode "Details"

"The brave and magnificent Ozan, who writes his own examine text."

— Ozan's examine text, RuneScape

Sometimes actors want to have a say in the words they're given; sometimes they want to stretch their artistic muscles; sometimes they look at the scripts they have to do and think, "I could do better than this!" When this happens, and the producers are on their side (or the network is), you have something written by a cast member.

Much less prevalent than Directed by Cast Member, particularly in these days of arc-driven television. Writing is less glamorous than directing, for one thing, and it's harder to develop a story from scratch than to bring someone else's to the screen.

Key to both of these tropes is that the actor gets into writing or directing through the show they're on, without having a previous background in it (let alone being the series creator).

As the examples show, sometimes non-dramatic Expanded Universe works can be written or co-written by actors, for name-recognition value. Often these works focus on the character the actor plays in the show.

For the opposite direction of crossover, see Descended Creator and Creator Cameo. For shows where the cast and the writing staff heavily overlap, see Cast Full of Writers.

Michael Tatum, Patrick Seitz and Caitlin Glass, just to name a few have written for several of the shows they star in.

  • They later co-wrote and played in The Last Duel. Nicole Holofcener wrote the part of Jodie Comer, meanwhile.

• Charles Laughton hated the Dalton Trumbo-written dialogue he was initially given in Spartacus, so Peter Ustinov rewrote all of the scenes featuring the two of them, which placated Laughton enough to complete his portion of the film.

• Enzo Cellucci and Ash McNair, who co-star in the Short Film Class (2021), also co-wrote the film.

• Nia Vardalos wrote My Big Fat Greek Wedding and its sequel, Connie and Carla, and I Hate Valentines Day (which she also directed). She also co-wrote Larry Crowne, where she has a brief voice role.

• An unusual example exists in the case of Doctor Who Meets Scratchman, which was written by co-stars Tom Baker and Ian Marter but was ultimately never picked up for production. Had it actually been produced and released, it would've been an eclectic, Terry Gilliam-esque game of cat-and-mouse through time and space between the Doctor & company and Satan (named "Scratchman" for whatever reason) that would've culminated in a final battle on a giant pinball table. The script was finally realized as a novel by Baker (alongside James Goss — Marter having sadly passed away in the '90s) in 2019.

Marter and Tom Baker co-wrote a speculative script for a Doctor Who movie during their time together on the show, called Doctor Who Meets Scratchman, which eventually ended up as a novel called simply Scratchman — as Marter had died in the meantime the novelisation was a collaboration between Baker and Whoniverse writer James Goss.

His first sketches were the Colambo sketches, in which he played the titular character, and the success of those bits allowed him to join the writing staff full-time in addition to puppeteering. By the end of his tenure, he was the show's head writer.
  • While not a specific sketch, Carroll Spinney (Big Bird and Oscar the Grouch) gave the idea to have real kids appear in unscripted bits with the Muppets. He also wrote the plot outline for the special Big Bird in China.
• Several songs on The Sunny Side Up Show were written by the show's hosts.
• During their days on Head of the Class, Brian Robbins and Dan Schneider had their first writing credits on the "Will The Real Arvid Engen Please Stand Up?" episode. And the rest is history.
• Brian Krause (Leo) is the only cast member of Charmed to co-write an episode: he has co-story credit on "Sense And Sense Ability." He's said the finished product was different from what he turned in.
• Unlike Directed by Cast Member, very few episodes of the Star Trek franchise qualify - in fact, the only ones are DS9's "The Muse" (co-written by Majel Barrett-Roddenberry) and Voyager's "Life Line" (co-written by Robert Picardo). Both focused on those actors' characters. (Walter Koenig wrote "The Infinite Vulcan" for the animated series, but due to budget limitations, wasn't a cast member on that show.)
• Barry Watson wrote an episode of 7th Heaven (not one of the two he directed).
• Robert Culp loved doing this on his shows: Trackdown, I Spy, and The Greatest American Hero all had episodes he wrote (and directed). In addition, he wrote one of the two episodes of Cain's Hundred on which he guest-starred.

• Jack Klugman, who made no secret of his views on the standard of writing in TV, wrote or co-wrote four episodes of Quincy, M.E. in addition to having showrunner Glen A. Larson thrown off the show and eventually getting writers more to his liking. Including his own brother and sister.
• Don Adams co-wrote two episodes of Get Smart.
• Peter Falk wrote one script for Columbo, in which the Lieutenant is romanced by a Femme Fatale. He held it back until finding the perfect co-star: Faye Dunaway, who turned the role into an Emmy.
• Roger Smith wrote several episodes of 77 Sunset Strip.
• Done quite a bit on The X-Files, especially in later seasons. David Duchovny wrote (and directed) two episodes: "The Unnatural" and "Hollywood AD" while co-developing storylines for seven others. Gillian Anderson wrote (and directed) season seven's "all things." William B Davis (who plays The Smoking Man) wrote "En Ami."

• Michael Imperioli wrote several episodes of The Sopranos. This is reflected in Christopher Moltisanti's interest in film and screenwriting.

He went on to write more episodes of Little House on the Prairie than anyone else, as well as create another successful vehicle for himself in Highway to Heaven.

• Patrick Labyorteaux (Bud) wrote the episode "JAG TV" on JAG.
• Three of CSI: NY cast members tried their hands at writing episodes. Gary Sinise worked on the story line for "Live or Let Die" about a stolen donor liver, and wrote the screenplay for "Turbulence" in which a man posing as an Air Marshall is killed during a flight that Mac is on. Melina Kanakaredes wrote "Grounds for Deception" where Stella goes to Greece chasing a suspect - an ep which unfortunately drew mixed reviews from fans. Finally, Carmine Giovinazzo wrote "Sanguine Love," about the murder of a member of a vampire-like cult. This one was much better received by viewers.
• David Faustino (Bud) co-wrote one episode of Married... with Children.
• Diahann Carroll wrote an episode of her series Julia.
• James Roday Rodriguez has written or co-written over a dozen episodes of Psych, one of which was an elaborate homage to Twin Peaks (his "favorite show of all time, hands down").

• St. Elsewhere:
  • The story of "Hearing" was written by guest star Robert Daniels, who played Lee Tovan in that episode.

• Ellen DeGeneres is credited for the story of Ellen's coming out episode.
• Jerry O'Connell and John Rhys-Davies each received a story credit on Sliders - O'Connell got a few such credits (such as on "Way Out West") while Rhys-Davies only got it for "The Exodus, Part 1." In the latter case, it was the culmination of his feud with the producers and network: they purchased an outline he pitched as an example of how the show could better use its potential, drastically rewrote it into the kind of embarrassing B-movie he'd been complaining about, and since he had just been fired for his outspokenness, reduced his character to a mumbling brain-damaged state, fatally shot him in the heart, and left his corpse behind on a radioactive planet... which immediately exploded.
• Yaphet Kotto wrote one teleplay in each of the last three seasons of Homicide: Life on the Street — "Narcissus", "Secrets", and "Self-Defense". According to him, this arose out of boredom, as he was a contracted regular cast member on the show, but due to his role as Da Chief, often had only a couple of scenes per episode.
• Paul Gross wrote or co-wrote some of the most memorable episodes of Due South, including the introduction of Kowalski and the two-part series finale.

• Glee's Chris Colfer wrote season five's "Old Dog, New Tricks."

• Sara Gilbert received a story credit on Roseanne for the Season Episode "Don't Make Me Over."
• Taken to the extreme on The Red Green Show, as Steve Smith (who played the title character) wrote all 300 episodes. Rick Green (Bill) also wrote for most of the first eight seasons, and other episodes included contributions from Peter Wildman (Buzz Sherwood), Bob Bainborough (Dalton Humphrey), Jeff Lumby (Winston Rothschild), and Patrick McKenna (Harold Green).
• The Wiz had two of the leads of the 2015 NBC production, Elijah Kelley (the Scarecrow) and Ne-Yo (the Tin Man), help write a new song, "We Got It". In it, Dorothy and her friends proclaim that The Power of Friendship can help them defeat Evilene and get their desires granted.
• Maid Marian and Her Merry Men was created and written by its star Tony Robinson, however, co-stars David Lloyd and Mark Billingham contributed a lot of ideas and ended up being co-credited for a couple of episodes.
• Schitt's Creek was created by father and son duo Eugene Levy and Daniel Levy, who play father and son on the show. Daniel is also the Showrunner and writes most of the episodes.

• Robert Llewellyn wrote the Red Dwarf episode "Beyond a Joke". And then it was rewritten by Doug Naylor.
• Rowan Atkinson co-wrote the first season of Blackadder with Richard Curtis.
• A songwriting example: the LazyTown song "Techno Generation" was co-written by Jodi Eichelberger, Stingy's puppeteer.
• Return of Ultraman: Shin Kishida, who played Ken Sakata and was a sci-fi literature enthusiast, wrote Episode 35, starring the psychedelic iceberg kaiju Prizma. This probably explains why Ken plays such a large role in the episode.
• Ellen Corby, who played Grandma Walton, wrote two episodes of The Waltons.
• Cobra Kai: The showrunners allowed the actors a lot of input into how their characters had changed since the events of the original The Karate Kid movies, along with fleshing out their backstories.
  • Most of Johnny Lawrence's backstory (having an abusive home life and seeing Kreese as a father figure), was created by William Zabka during the first film as a way to get a better feel for the character.
  • Martin Kove, similarly, long ago had developed the idea that Kreese was a Shell-Shocked Veteran whose wartime experiences traumatized him into cruelty. This was adapted in the show's third season, which focuses heavily on Kreese's Start of Darkness.
  • In season 3, Tamlyn Tomita worked with the creators to offer a more accurate depiction of Okinawan culture than The Karate Kid Part II, helping to translate script passages into Okinawan dialect and choreographing Kumiko's dance scene.
  • Yuji Okomoto had a long phone conversation with Josh Heald soon after he was cast, where he offered suggestions about Chozen's growth since The Karate Kid Part II. He was surprised and flattered at how many of his ideas made it into the show.
• Besides being credited as consultant producer in Season 2 of American Gods (2017), Orlando Jones reveals in several interviews that he ended up being roped into writing the character bibles and scripts for several characters, including Bilquis, Salim, the Jinn, Sam Black Crow, Mr. Ibis, main characters Shadow and Laura Moon, and his own character Mr. Nancy.
• Patrick McGoohan wrote three episodes of The Prisoner (1967): "Free For All" (under the pseudonym "Paddy Fitz") and the two-part Grand Finale, "Once Upon a Time"/"Fall Out".

• Jeremy Lloyd (Bobby Dutton) helped David Croft rewrite the first three episodes of It's Awfully Bad for Your Eyes, Darling... to be funnier.
• Doctor in the House:
  • The entire second series of Doctor in the House was co-written by Graeme Garden and Bill Oddie; Garden appeared in the episode "Doctor on the Box" as the presenter of the programme that has been filmed at St Swithin's - which turns out to be a viciously critical examination of the students' drunken antics at the taxpayers' expense.
  • Before leaving the series, George Layton wrote a number of episodes of Doctor at Large and Doctor in Charge under the pseudonym Oliver Fry. His contributions to Doctor at Sea, Doctor on the Go, and Doctor at the Top were under his own name.

They had the whole feud written out by the time they got to Myrtle Beach, SC.
• Chris Jericho was the one who came up with The Bet storyline involving himself, Christian, Trish Stratus and Lita, as the WWE creative team had no plans for him or Christian.

Radio

• In 1955, The Archers had an episode where Grace Archer, the wife of Phil, was killed off. (It may or may not have been a coincidence that the episode went out on BBC radio the very night commercial television began.) The script had Grace's fate be conveyed in the final line of dialogue thus: "She... she died in my arms... on the way to hospital," but Norman Painting, who played Phil, suggested the line go "In my arms... on the way to hospital... she's dead!" Suffice to say that not only was this one of the most talked-about episodes of the soap, but Painting went on to write many, many episodes (and the book Forever Ambridge - 25 Years of The Archers), as well as act in them.
• Louise Jameson, who played Leela in Doctor Who, wrote a Fourth Doctor and Leela audio drama for Big Finish Doctor Who, "The Abandoned."
