We must admit we were sceptical when talented British actor Tom Sturridge got pushed off sci-fi flick Jumper, to make way for wooden Star Wars actor Hayden Christensen, because an increased budget necessitated a bigger name. But judging by this trailer, Hayden shows every sign of being well-cast in the role of a young man who can teleport at will. Jumper is from Doug Liman, the director of Go, The Bourne Identity and Mr & Mrs Smith, and also features Jamie Bell, Rachel Bilson and Samuel L Jackson. We believe Jamie’s got a much bigger role than the trailer suggests – presumably US audiences don’t know who he is, so it’s all about Hayden. We’re not too sure about Jamie’s haircut, mind you.
