Shoot 'Em Up amounts to an action packed "chase" movie. Clive Owen plays the mysterious Smith who rescues a newborn baby that he delivers himself in the middle of a gunfight. He's chased by Paul Giamatti, an ex-FBI profiler turned bad guy, trying to retrieve the baby from Smith. Monica Bellucci plays a prostitute, with her own short back story, that gets caught in the action on the side of Smith.
The action is quite stylized with a fair amount of humor, which Clive Owen plays seriously. He always has carrots, he grows himself, which he's constantly eating and using as a weapon. There are a lot of refreshing small ideas that you don't always find in this kind of action movie. Most of what you learn about Smith is from the villain, Giamatti's character as he profiles him. It turned out to be a fun and violent, carrot packed movie that doesn't make you think too much.
