All of the actors you've just listed would be bad picks.
Tom Willing - I have no idea who that is nor can I find anything about him.
Daniel Radcliffe - Harry Potter as Goku? He's too young looking and he would have to go on a heavy training program for the part.
Jackie Chan - As much as I'm a fan of Jackie Chan, there is no way Jackie Chan could fit the part.
Hayden Christensen - Anakin Skywalker?! This guy's terrible at acting, there's no way I'd pick him for the role of Goku.
Jay Lee - No idea who that is.
Christian Bale - Good actor, but he would not fit the part of Vegeta.
Leonardo DiCaprio - No, just no. I thought people would think of him as playing Trunks, but Vegeta? No way.
Tom Welling is the actor who performed as Crock Kane in the tv series "smallville"
Jay Lee for goku? man...he's too short for that.........he would be the best vegeta ever.
Leonardo DiCaprio is noway can be fit trunks because his age problem, and only younger actor can handle that job. beside Leonardo perform a badass in blood dimond. I don't think people would accept a gang perform trunks.
Hayden Christensen...he has good looking and body type.
Daniel Radcliffe: he's been grown alot since gablet of fire. I doubt he will handle goku as well.
Jackie Chan....he's a comedian.....but I think I can't imagine how is he look in goku..
well, that's my oppinion.
