During the closing credits, there is an additional scene in the War Room where the President prepares a latte for General Monger and pushes the wrong big red button.

Nice team chemistry
31 October 2013 | by See all my reviews

Susan Murphy (Reese Witherspoon) is a woman who got upsized by a meteorite on her wedding day. B.O.B. (Seth Rogen) is a gelatinous, brainless creation after an experiment on a tomato went wrong. Dr. Cockroach (Hugh Laurie) is a scientist who turned himself into a hybrid. The Missing Link (Will Arnett) is a creature found frozen and revived. And giant mutant larva Insectosaurus is a product of nuclear testing. The government has secretly collected these monster and now they need them to fight alien Gallaxhar (Rainn Wilson).

DreamWorks has gathered all the iconic 50s sci-fi B-movie creations, and formed a pretty cohesive team. It's surprising that the limited backstory allowed the characters to gel so well right off the bat. It's probably due the fact that these characters seem so familiar to us. It also helps that the actors do some great voice work.

The story itself has one major problem. The movie is basically split in two parts. The pacing slows down dramatically in the middle after a high intensity fight at the start. However the comedy works well especially the brainless BOB. I think this team has good potential.
