Chris Columbus directed both first 'Harry Potter' films, 'Philosopher's Stone' and 'Chamber of Secrets'. During an interview for the promotion of his most recent movie 'Pixels', he mentioned the trio.
Columbus told me that he was surprised that actors Daniel Radcliffe, Emma Watson and Rupert Grint ended up being as great as they were.
“I’d be lying if I said I knew by movie seven they would have turned into the people that they did,” Columbus said. “We cast them because they felt really so perfect for the roles.” He said the first movie has a lot more cuts than the rest because the kids had such a hard time crafting a performance. The second film fixed that though and then, when Columbus stepped back to produce the third film, everything clicked into place. “By the time we got to three they had really developed into terrific actors,” he said. “I was very proud of that. I look back on it and I’m extremely proud of it, and I don’t tend to go back and think about old stuff that much.”
