 CONT: When Brom and Eragon are riding to Daret, it can clearly be  seen that Brom is leading the way. Then, in a shot when the camera  flies over the two riders from behind, it is Murtagh riding instead  of Brom. You can tell by the larger cape, longer hair, and the fact  that he is carrying a bow, which Brom never had. Then in the next  shot it is Brom again.
