Writer-director Guy Ritchie messed mercilessly with the traditional story of Sherlock Holmes in those two movies starring Robert Downey Jr.—but they still managed to be fun action flicks. So it's no big surprise to see him revamping the King Arthur myth in ways we've never imagined. Here, we see young Arthur (Charlie Hunnam from "Sons of Anarchy") as a con man/gangster in his pre-king days. (Ritchie's Lock, Stock and Two Smoking Barrels roots are showing.) Eventually, he pulls a sword out of a stone, and we get an insane orgy of special effects that wouldn't be out of place in a Dungeons & Dragons movie. It's hip, it's cool, it's modern. It's like an MMA music video crossed with Lord of the Rings. This ain't your father's King Arthur, no siree! Ritchie really hopes you like this one, because he's planning to make five more of them.126 minutes PG-13.
