SCI FI Wire has an exclusive behind-the-scenes featurette for DreamWorks Animation's upcoming 3-D sci-fi spoof movie Monsters vs. Aliens, featuring star Rainn Wilson.

Monsters vs. Aliens features the voice of Reese Witherspoon in her first animated feature as bride-to-be Susan, a woman who grows to 49 feet 11 inches tall. She is labeled a mutant by the U.S. military and placed into secure custody with other so-called "monsters": Dr. Cockroach, Ph.D., an insect-like scientist voiced by Hugh Laurie; Missing Link, an ancient fish-man voiced by Will Arnett; B.O.B., a brainless yet witty gelatinous blob voiced by Seth Rogen; and Insectosaurus, a furry, childlike 350-foot-high grub. It seems hopeless for Susan until aliens (led by Gallaxhar, voiced by Wilson) invade our planet—and the president (voiced by Stephen Colbert) and Gen. W.R. Monger (Kiefer Sutherland) decide those monsters are good for something after all.

Monsters vs. Aliens opens March 27.
