Michael Davis' Shoot 'Em Up will never be accused of false advertising. Clive Owen is in the wrong place at the wrong time when he encounters a woman and her newborn being pursued by plenty of armed men, and because he's a potential witness, they take aim at him. Bad move. Next thing you know, bullets are flying, he's holding a baby, and a truly psychotic former FBI profiler (Paul Giamatti) and his enormous squad of redshirts are after him.
Why? Dude, who cares? The movie is called Shoot 'Em Up. There's something about baby farms, presidential candidates and gun control, but whatever. Davis boils his movie down into gunfight after gunfight after gunfight, each one more over-the-top than the last.
Owen, droll and deadpan as ever, shoots people while parachuting, while riding a merry-go-round and while holding the baby (an homage to John Woo's Hard Boiled, one of the inspirations for this film and required viewing for action-movie fans). He even shoots people while having sex with Monica Belucci, the lactating hooker he recruits to help him out. Yes, you read that right. Body count high, plot points low, title accurate.
