Reese Witherspoon is a Monster -- No, an Alien!

Reese Witherspoon will lend her voice talents to DreamWorks Animation’s latest film Monsters vs. Aliens, according to Variety.

The top-earning actress in Hollywood will join Hugh Laurie, Will Arnett, Seth Rogen, Rainn Wilson, Stephen Colbert, Kiefer Sutherland and Paul Rudd in DWA’s first film produced in Ultimate 3-D technology.

Here’s what Variety had to say about the plot: “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).”

Monsters vs. Aliens won’t be released for at least another year — March 27, 2009!
