British tough guy Tim Roth refuses to regret not grabbing a lead role in the Harry Potter movie franchise - because countryman Alan Rickman is the perfect PROFESSOR SEVERUS SNAPE. Roth was offered the dark role before Rickman but turned it down because he thought the character was "under-developed". The Reservoir Dogs star reveals, "There were only a couple of Harry Potter books out at that point, and Snape seemed under-developed. "I've watched the films, and Alan Rickman does a good job. If you pass on a project and it turns out well, then it was probably the right thing to do, but, at that point, I didn't really want to be on a lunch box."
