** Magister Illyrio Mopatis went from Ian McNeice to Roger Allam

** Fans will get to see some footage of Eric Stoltz as Marty in the upcoming Blu-Ray release of the ''BTTF'' trilogy.

** Genevieve Bujold was originally cast as Nicole Janeway on ''StarTrekVoyager''. When she bailed from the show after only three days of filming, she was replaced by Kate Mulgrew as ''Kathryn'' Janeway. This is quite possibly the most brilliant thing the producers ever did with ''Voyager'', because while fans [[BrokenBase take issue with just about every aspect of the show]], almost all of them, including SFDebris, agree that Mulgrew's performance is by far the best thing going for the character.

* ''{{Cheers}}''. Sam Malone was initially Fred Dryer. When he was replaced by Ted Danson, Sam became an ex-baseball player due to Danson's thin frame. Dryer would have a recurring role as Sam's sports reporter friend Dave Richards. Julia Duffy was originally cast as Diane Chambers. She appeared in one episode in Season 1 as Diane's best friend Rebecca Prout.

** Genevieve Bujold was originally cast as Nicole Janeway on ''StarTrekVoyager''. When she bailed from the show after only three days of filming, she was replaced by Kate Mulgrew as ''Kathryn'' Janeway. This is quite possibly the most brilliant thing the producers ever did with ''Voyager'', because while fans [[BrokenBase take issue with just about every aspect of the show]], almost all of them - including such prominent critics as SFDebris and ConfusedMatthew - agree that Mulgrew's performance is by far the best thing going for the character.

** No big lose when it came Nancy Cartwright, as she'd probably would have left South Park for the same reason that Isaac Hayes left the show (as she's also a Scientologist).

* Christopher Collins voiced Mr. Burns in a couple of first season episodes of ''TheSimpsons''. In the first episode produced, "Some Enchanted Evening," besides voicing a TV host, he recorded Moe's lines before they were dubbed over by HankAzaria, who assumed the part from then on.

* ''MobileSuitGundam'' features a very strange example involving a mechanical design as opposed to an actor. In the CompilationMovie trilogy the G-Fighter, a gimmicky MechaExpansionPack for the Gundam was replaced with the more sensible Core Booster, an add-on for the small jets developed as escape pods for the RX-series MS that allowed them to function more effectively as fighters. The G-Fighter can still be seen in a few shots using footage from the TV series.

* The role of Willard in ''ApocalypseNow'' was originally played by Harvey Keitel, but he was fired about a week into shooting and replaced by Martin Sheen. Sheen later suffered a heart attack during filming, and several scenes in the finished film actually feature his stunt double instead.

* One of the actors in ''{{The Room}}'' quit the film before filming his big scene of catching Lisa and Mark together and berating them for betraying Johnny. Rather than get a new actor, Tommy Wiseau kept all the scenes that had been shot, and simply put another, never before seen character in the new scene.

* Billy Wilder's ''Kiss Me, Stupid'' began filming with PeterSellers in the key role of a struggling composer, but when Sellers suffered multiple heart attacks, the film was reshot with Ray Walston in the role.

* Frank Sinatra was originally cast as Billy Bigelow in the film version of ''Carousel''. Because they had to shoot each scene twice - once in standard 35mm film and once in the new 55mm film - he left the production, and Shirley Jones' ''Oklahoma!'' co-star Gordon [=MacRae=] was cast instead. Though nothing was ever filmed, they had started sound recordings before Sinatra left. Ironically, a few weeks into production, a conversion process was discovered, rendering multiple takes unnecessary.

* At least some of ''Sharpe's Rifles'' was shot with Paul [=McGann=] as Sharpe, but owing to an injury he had to be replaced by Sean Bean.

* Subverted on ''TheATeam'': Someone named Tim Dunigan played Face in the two-part pilot, but the episodes were ''not'' reshot when Dirk Benedict was cast. This also somewhat subverts TheOtherDarrin, as Dunigan is not associated with the role at all or ever mentioned, as often happens with that trope.

* GrowingPains had a different actress playing Carol in the pilot; her scenes were reshot. This has been mysteriously forgotten about; the actress's name is rarely, if ever, mentioned, and little to nothing is known about her.
* Bob Saget replaced John Posey in FullHouse; this is why Michelle seems somewhat older when Danny walks in the room. Reportedly, the producers wanted Saget from the start, but he was unavailable due to being employed as a "comic correspondent" for CBS' short-lived "Morning Program" newscast.

** And that Jan Werich reminded the production crew of Santa rather than a supervillain. Donald Pleasence, on the other hand...

** Genevieve Bujold was originally cast as Nicole Janeway on ''StarTrekVoyager''. When she bailed from the show after only three days of filming, she was replaced by Kate Mulgrew as ''Kathryn'' Janeway. This is quite possibly the most brilliant thing the producers ever did with ''Voyager'', because while fans [[BrokenBase take issue with just about every aspect of the show]], almost all of them firmly agree that Mulgrew is '''phenomenal'''.

**Could Charisma Carpenter's breasts be included in this list?

*Karri Turner was originally supposed to be the lead voice actress for ''SouthPark'' and appeared in the unaired pilot as Wendy, Ms.Crabtree, and the other female characters. She wound up replaced by Mary Kay Bergman in the series proper, as the creators felt her voice wasn't distinct enough. Interestingly, the first choice before Turner was Nancy Cartwright, who refused to work on the show due to its crude content (OrSoIHeard).
