From the studio that brought you Kung Fu Panda and Madagascar 2, comes a hilarious and out-of-this- world animated adventure.Monsters vs Aliens, opening at the BFI IMAX, marks the first 3D collaboration between IMAX and Dreamworks.  

When California girl Susan Murphy (Witherspoon) is unwittingly clobbered by a meteor full of outer space gunk on her wedding day, she mysteriously grows to 49-feet-11-inches tall.  The military jumps into action and Susan is captured and put into a secret government compound.  There, she is renamed Ginormica and held along with a ragtag group of Monsters:  the brilliant but insect-headed Dr. Cockroach, Ph.D. (Laurie); the macho half-ape, half-fish, The Missing Link (Arnett), the gelatinous and indestructible B.O.B. (Rogen); and the 350-foot grub called Insectosaurus.  Their confinement is cut short, however, when a mysterious alien robot lands on Earth and begins storming the country.  In a moment of desperation, The President (Colbert) is persuaded to enlist the motley crew of Monsters to combat the alien robot and save the world from imminent destruction.
 
Other stars in this out-of-this-world ensemble include Keifer Sutherland as General W.R. Monger, an armed forces lifer who’s finally found a use for his collection of detained Monsters…battling the alien invader; and Paul Rudd as Derek Dietl, Susan’s selfish fiancé, who has outgrown his current weatherman position and aspires to network news greatness.
