DreamWorks Animation has revealed the voice cast and released a new photo for their 2009 computer animated 3D film Monsters vs. Aliens.

Based on the horror comic Rex Havoc, the film attempts to reinvent the classic 1950’s monster B-movie starring Reese Witherspoon as Susan Murphy, a California girl who, on her wedding day, has the bad luck to be hit by a meteor, which causes her to grow to be 49 feet, 11½ inches tall. Captured by the military, she’s renamed Ginormica. Here are 6 other reasons why I can’t wait to see this movie, and the rest of the voices cast:

• Rainn Wilson – the evil alien Gallaxhar
• Hugh Laurie - Dr. Cockroach, Ph.D.
• Seth Rogen – the jellylike B.O.B.
• Will Arnett – the half-ape, half-fish Missing Link
• Kiefer Sutherland – General W.R. Monger
• Stephen Colbert - The President

Monsters vs. Aliens hits theaters on March 27th 2009.
