Monsters vs. Aliens: Mutant Pumpkins from Outer Space

When evil aliens pose as harmless pumpkins in a bid to take over planet Earth on Halloween night, it's up to Susan (voice of Reese Witherspoon), B.O.B. (voice of Seth Rogen), Dr. Cockroach (voice of Hugh Laurie), and the Missing Link (voice of Will Arnett) to thwart the invasion and save the day.
