"I don't think Alfonso was a big expert on Potter either. He was feeling his way through it more than I was"
- David Thewlis
About this Quote
This quote by David Thewlis is describing his experience dealing with the Harry Potter films. He is indicating that his co-star Alfonso Cuarón was not as experienced about the Potter universe as he was. Thewlis recommends that Cuarón was feeling his method through the movies, discovering as he went, while he was more knowledgeable about the source product. This could be due to the truth that Thewlis had checked out the books before being cast in the movies, while Cuarón had not. Thewlis' quote suggests that he was more comfy with the product than Cuarón, and that he was more of an expert on the Potter universe. This might be why Thewlis was cast as Remus Lupin, a character with a deep connection to the Potter universe, while Cuarón was cast as the director of the 3rd movie in the series.
"If the Police could do a reunion... One of the biggest jerks I ever met was Sting. If he can do it, then anyone can do it. It's not that big a deal. And the Eagles! They did it! They severely hated each other. It's just rock and roll"
