No, Daniel Radcliffe was in the Harry Potter movies, as were the other two. I believe the names you're looking for are Benneth Stiller and O.N. Wilson.
Another one on my list would have to be Jake Gylanhaal.
Yet another mumbler; He's mumbled in everything from Donny Darko to Brokeback Mountain...I can't count the amount of times I've had to adjust the volume to ridiculous levels.
Yes- Colin Firth... I seemed to have missed a meeting there... looks and acts like a middle aged, middle manager- I seem to entirely miss exactly WHY hes supposed to be sex on legs. Quite apart from his annoying movie persona I fail to see any range in his acting either...
