This is a stupid movie, I can't believe I bought it. Two brothers, one a hero, the other a bumbler go on a quest. There are some fairly interesting computer generated special effects, I bet half the movie was filmed in front a a blue screen.
Natalie Portman plays the most sensible character and they have a great outfit for her. It does get slightly better in the second half. NOTE: there is a scene with partial nudity, the members of the quest are captured by a bunch of topless warrior women. I would pass on this one.
