The best Body-swap comedies can be romantic or terrifying, but mostly they are played for laughs. Strictly speaking, a body-swap movie is one where there is an exchange between two people. However, the term is also applied to movies where characters become a different (usually older or younger) version of themselves. They provide actors with the opportunity to play completely against type - and, often, against age or gender. While there's usually plenty of wackiness and hi-jinks in body-swap comedies, there are also frequently moments of real tenderness and emotion.

The process is, after all, a transformative experience. By inhabiting someone else's body, the characters, inevitably learn important truths about themselves. These body-swap movies also offer a lot of attraction to top-name actors, solely for the chance to act outside their wheelhouse and try out someone else's shoes. Names like Tom Hanks, Jamie Lee Curtis, Jennifer Garner, and Ryan Reynolds have taken their turn in these body-swap comedies in both original movies as well as remakes of classics, as this is a genre that has been around for decades.
