Ol' Dudley...

Came here to say the same, he did a terrific job.

Just finished it, and yes, it was a nice surprise to see him being confident, eccentric and up to the game in all scenes with Bale. If I was an actor, certainly a green one, it would be quite scary to act on scene with such a talent like Bale, with his legendary and intense status. Melling did more than fine. I really enjoyed this movie!
