Universal announced via press release that Leslie Mann has been tapped to star opposite Ryan Reynolds and Jason Bateman in The Change-Up, which is expected in theaters in August 2011. The film — which follows a family man (Bateman) who swaps bodies with his slacker best friend, who is played by Reynolds — is being directed by David Dobkin, with Neal Moritz producing. The Hangover writers Jon Lucas and Scott Moore served as the film’s writers.

Mann, the wife of über-director Judd Apatow, last starred in Funny People.
