Movies like Multiplicity

Being John Malkovich dives into the surreal as characters gain the ability to enter the mind of the titular actor, leading to a unique multiple identity situation. The film's offbeat and existential humor draws parallels to the identity crisis themes presented in Multiplicity.

The Parent Trap, while different in its kid-friendly tone, revolves around the charming antics of identical twins (played by a single actress, Lindsay Lohan) trying to reunite their separated parents. The doppelganger shenanigans offer a lighter take on mistaken identities and could appeal to fans of duplication comedy like Multiplicity.

Austin Powers: The Spy Who Shagged Me brings back Mike Myers in multiple roles, showcasing a comedic range similar to Multiplicity. With time travel antics and a host of memorable characters, it's a groovy choice for fans looking for more than one dose of a beloved actor.

The Nutty Professor features Eddie Murphy in a tour-de-force performance, playing multiple characters through the use of transformative makeup and effects – much like Michael Keaton's portrayal of his character's clones in Multiplicity. Fans of the high-energy comedy and the theme of one actor in multiple roles will find plenty to enjoy here.

Jim Carrey's split personality antics in Me, Myself & Irene channel a similar vibe to Keaton's performance in Multiplicity. With the Farrelly brothers' signature comedic style, this movie tackles the concept of one body with multiple personalities, albeit in a more exaggerated, slapstick form.

Dave takes the idea of doubling and identity into the political realm, with Kevin Kline playing both a regular guy and the President of the United States. This light-hearted and charming flick echoes Multiplicity's theme of an ordinary man finding himself in extraordinary circumstances.
