Harry Potter - Harry Potter Stars Tested Columbus On Set
British actor Matthew Lewis and his Harry Potter co-stars risked the wrath of director Chris Columbus on the early wizard movies - because they were always "messing and joking around" during filming.
Lewis was a pre-teen when he landed the role of Neville Longbottom in the franchise, alongside leads Daniel Radcliffe, Rupert Grint and Emma Watson.
The 22 year old admits the child stars loved to joke around on the set of the first two movies, Philosopher's Stone and Chamber of Secrets - and Columbus had a hard task on his hands trying to control them.
Lewis tells Britain's The Sun, "I imagine there were times on the first two films where Chris Columbus was thinking 'For crying out loud, they are not doing what I want them to do'.
"We were messing and joking around. But he never lost his temper. At 11 or 12 you didn't treat it as a job. It wasn't until 15 that I saw it as being a serious career."
