Monsters vs. Aliens

Monsters vs. Aliens is a 2009 American animated science fiction comedy film directed by Conrad Vernon and Rob Letterman and written by Letterman, Maya Forbes, Wally Wolodarsky, Jonathan Aibel and Glenn Berger. Produced by DreamWorks Animation, it is the first installment in the Monsters vs. Aliens franchise. The film stars Reese Witherspoon, Seth Rogen, Hugh Laurie, Will Arnett, Kiefer Sutherland, Rainn Wilson, Paul Rudd, and Stephen Colbert. The film involves a group of misfit monsters tasked by the United States Armed Forces to stop the invasion of an extraterrestrial villain and save the Earth in exchange for freedom.

It was DreamWorks Animation's first feature film to be produced in a stereoscopic 3D format instead of being converted into 3D after completion, which added $15 million to the film's budget.

Monsters vs. Aliens was released in the United States on March 27, 2009, by Paramount Pictures, to mixed reviews from critics. It was a box-office success, grossing $381 million on a $175 million budget. It was followed by two television specials, Mutant Pumpkins from Outer Space and Night of the Living Carrots, and a television series in 2013.
