Harry Potter's Tom Felton Originally Thought Gary Oldman Was a Cleaner on the Set

At LeakyCon Dallas earlier this month, several Harry Potter cast members got together to share their experiences of what it was like to work on such a huge set over the years. Tom Felton (Draco Malfoy), Scarlett Byrne (Pansy Parkinson), Afshan Azad (Padma Patil), Georgina Leonidas (Katie Bell), and Tiana Benjamin (Angelina Johnson) spoke about the franchise's impressive cast, and how the young actors got help from their older, more experienced co-stars at the time.

According to FanFest, Leonidas shared that she was struck by how down-to-earth Helena Bonham Carter (Bellatrix Lestrange) was. "There was no hierarchy on set," she explained. "We were all there to make a film, and they made you feel like you wanted to be there.”

Azad said she learned a lot from Emma Thompson (Professor Trelawney), who encouraged her to stay in school no matter what. Now the actress claims that's the advice she gives to younger actors.

Felton added that they got to learn from some of the greatest actors in the world, a situation that mimicked their on-screen education as new wizards. “Because we were young wizards learning from older wizards and the reality is that we were young, crap actors learning from the best,” Felton said.

Despite these veteran actors coming in with years of accolades to their credit, they weren't all famous to the child stars at first. That point was made clear when Felton shared that he originally thought now-Academy Award winner Gary Oldman (Sirius Black) was a cleaner when he first saw him on set.

The cast had nothing but wonderful (and hilarious) things to say about their Harry Potter experience, which only makes the beloved series all the better.
