John Debney has taken over scoring duties on the upcoming comedy The Change-Up. Theodore Shapiro has originally been attached to write the music for the film as reported last month. The Change-Up is directed by David Dobkin (The Wedding Crashers) and stars Ryan Reynolds, Jason Bateman, Leslie Mann, Alan Arkin and Olivia Wilde. The movie tells the story of a married guy who accidentally changes bodies with his single best friend and ends up pursuing a female coworker. Since our last posting, a red band trailer for the film has arrived and can be watched below. The comedy will be released by Universal Pictures on August 5, 2011.

As previously announced, Debney also has Garry Marshall’s ensemble comedy New Year’s Eve and the thriller The Double coming out later this year.
