Watch Monsters vs Aliens

Monsters vs. Aliens is a 2009 computer-animated 3-D feature film from DreamWorks Animation and Paramount Pictures. This is the first computer animated movie which will be produced in real 3-D instead of converting the film into 3-D after it is finished, which added $15 million extra to the film's budget.

The film was scheduled for a May 2009 release, but it was moved to March 27, 2009, so as to prevent competition with James Cameron's upcoming Avatar, which has since moved its release to December 2009. Monsters vs. Aliens stars the voices of Reese Witherspoon, Paul Rudd, Hugh Laurie, Seth Rogen, Will Arnett, Rainn Wilson, Stephen Colbert and Kiefer Sutherland.

This is Seth Rogen's second DreamWorks Animation film, the first being Kung Fu Panda.
