Eek! Monsters & Aliens!

Listen closely and you’ll recognize the monster’s voice as that of Will Arnett (of Arrested Development fame). “Exercise party gone wrong” is actually a promo for the upcoming Dreamworks animation, Monsters vs. Aliens, to be released on March 27, 2009. Cast includes Will Arnett, Reese Witherspoon, Seth Rogen, Kiefer Sutherland, Paul Rudd, Rainn Wilson, and Stephen Colbert. That's a ton of really cool celebrities!
