* In {{Jumanji}} Jonathan Hyde plays both Sam Parrish, Alan's father, and Van Pelt, the hunter. This highlights the fear Alan feels toward both characters.

* In ''{{WitnessForTheProsecution}}'', two roles are always double-cast for reasons which would be a huge spoiler.

* In the ''KingdomHearts'' series, Sora is voiced Miyu Irino in the Japanese version and Haley Joel Osment in English, while his [[EmptyShell Nobody]] Roxas is voiced by Kouki Uchiyama/Jesse McCartney. When ''Birth By Sleep'' came out, new hero Ven looked like Roxas and shared his voice actor, while masked antagonist Vanitas had Sora's voice actor. [[spoiler:The game revealed that Vanitas looks like Sora under his mask, as he's Ven's EnemyWithout and his extraction damaged Ven's heart, forcing him to bond with Sora's to survive and the bond caused Vanitas to shapeshift into a dark version of Sora. As for Ven-Roxas, at the end of the game Ven's half-destroyed heart merges with Sora's, and years later according to WordOfGod, when Roxas was birthed from Sora he got the remnants of Ven's heart, which is why he looks like Ven]].

Frequently in fiction, and especially in theatre, the same actor will [[ActingForTwo play multiple roles.]] Sometimes this will just be for the sake of convenience, and not meaningful to the plot; after all, say it's the theatre--if an actor is going to show up at the theatre every night to perform, you might as well take as much advantage of his or her skills as possible. However, sometimes there are reasons for the same actor playing two parts that are symbolic or have some subliminal impact in the story. Hence, SignificantDoubleCasting.

* {{Fullmetal Alchemist}}: The first anime had both Trisha Elric and Sloth being voiced by the same actress; Sloth ends up being the humonculus created when the brothers tried to transmute their mother

* In the AlternateShowInterpretation of ''{{Assassins}}'' that was produced on Broadway, [[LemonyNarrator the Balladeer]] "becomes" Lee Harvey Oswald. Played by NeilPatrickHarris.

* In the ''{{Futurama}}'' movie ''Bender's Big Score'', both Philip Fry and Lars Fillmore are voiced by BillyWest. [[spoiler: They're actually the same person, Lars is an aged time-travel duplicate of Fry who was disfigured by injuries he sustained during the events of the movie]]. However, since Lars' voice is heavily distorted, and BillyWest voices many other completely unrelated characters in the show, so even if the viewer does realize it's the same voice actor, many don't see the significance of it until TheReveal.

* In ''ReeferMadness'', one character who plays the MoralGuardian narrator also shows up in a number of other roles in the musical, including as {{Satan}} tempting the protagonists into using drugs. The implication confirmed at the end is basically that he is also an evil tempter in the MoralGuardian role.

** Similarly, Brent Spiner as both Puck and Owen Burnett, with the twist that the writers hadn't planned on it initially.

* In ''{{Gargoyles}}'', Kate Mulgrew played a bit role as Fox's mother. Then later she plays the voice of Titania, Queen of TheFairFolk. Coincidence? No. Turns out, they were the same person after all.

* Most of the named characters in ''TheWizardOfOz'' appear in Kansas at the beginning, and have similar roles in both worlds: the Wicked Witch/Mrs. Gulch as the antagonist, Professor Marvel/The Wizard as the charlatan who gets Dorothy into trouble, and three farmhands/traveling companions as moral support for Dorothy.

* When Prior goes into Heaven at the end of ''AngelsInAmerica'', each of the other seven actors in the show play a member of the CouncilOfAngels. When Prior wakes up afterwards in his hospital bed, he goes ''TheWizardOfOz'' on Belize, Emily, and Hannah ("AndYouWereThere!").

* In ''[[SymBionicTitan Sym-Bionic Titan]]'', the identity of the man behind G3 is all but explicitly stated--and one of the major giveaways is his voice actor. [[spoiler:Both he and Lance's father were voiced by Richard McGonagle.]]

* Dragon Ball Z Christopher R. Sabat voices half of the male cast. He regularly voiced Vegeta, Piccolo, Yamcha, Korin, Kami, Mr. Popo, Zarbon, Guru, Moori, Jeice, Burter, Recoome, General Silver, Shenron, Egor, and even filled in as the narrator for a couple of occasions.
** Stephanie Nadolny was also cast as easily a quarter of the smaller female roles such as Angela, East Kai, and Ms. Hamilton in Dragon Ball Z in addition to her voicing Kid Goku, Kid Gohan, and Goku Jr. throughout the entire run of the series.
* Speed Racer was a show that dealt with a cast of only half a dozen. Peter Fernandez voiced Speed himself, and Racer X. Corinne Orr voiced Trixie, and pretty much every other female and young boy in the show.

* In ''{{Ever17}}'', Takeshi and the Kid have the same voice actor, though they are not voiced on their routes and can only be heard on the opposite route. [[spoiler:This is to conceal the fact that the "Takeshi" and "Kid" that we see are actually the same person, and not the real characters played as on their routes.]] Oddly enough, [[spoiler:this is also subverted, as the real Takeshi and the second Kid also have the same voice actor, but there is no real reason for all three characters having the same voice actor in-universe: just a coincidence.]]
