Reese Witherspoon, Hugh Laurie, Will Arnett, Seth Rogen, Rainn Wilson, Stephen Colbert, Kiefer Sutherland and Paul Rudd have signed on to lend their voices to DreamWorks Animation's "
Monsters vs. Aliens."
Story, which reinvents the classic '50s monster movie as a modern-day action comedy, centers on California girl Susan Murphy (Witherspoon), who is unexpectedly clobbered by a meteor full of outer space gunk and mysteriously grows to 50 feet tall. She is captured and held in a secret government compound. The world learns that the military has been quietly rounding up other monsters over the years, including the brilliant but insect-headed Dr. Cockroach, Ph.D. (Laurie) and the macho half-ape, half-fish the Missing Link (Arnett).
