If I Were You (Portuguese: Se Eu Fosse Você) is a 2006 Brazilian comedy film directed by Daniel Filho.

The film follows the story of Cláudio, a successful publicist who owns his own agency, and Helena, his wife, a music teacher who takes care of a children's choir.

Accustomed to the day-by-day marriage routine, they occasionally argue.

One day they have a bigger fight than normal, which causes something inexplicable to happen: they switch bodies.

Terrified, Claudio and Helena try to appear normal until they can reverse the situation.
