The actor on playing Draco Malfoy, all-night fishing with his brother and taking a beating from Chadwick Boseman

Who is your favourite other school bully: Donovan from The Inbetweeners, Biff Tannen from Back to the Future, Heather Chandler from Heathers, Nelson Muntz from The Simpsons or Gripper Stebson from Grange Hill? Dr_J_A_Zoidberg
I have so much compassion for Draco [Malfoy], knowing that he is the result of piss-poor parenting on his father’s side. I know James Buckley from The Inbetweeners very well. His character is an example of a comedic bully. But as a lifelong fan of The Simpsons, I’m going to have to say my favourite is Nelson Muntz.

What’s the biggest fish you’ve ever caught? TopTramp
A 37lb 4oz common carp caught on the St Lawrence river in New York state 15 years ago. Chris, my older brother, got me into fishing, while he was my chaperone on Harry Potter. My mum chaperoned me for the first film, and my grandfather for the second. He looked so much like a wizard that [director] Chris Columbus cast him at the teachers’ table next to Dumbledore. Then my brother was commandeered. He was one of the worst chaperones in history – all he seemed to do was sleep the entire day – but that’s probably because we’d been up all night, fishing. Some days we’d leave set at 6pm, drive two hours back to Surrey where we lived, go straight to a lake, cast our rods, set up a tent, sleep – barely – for a few hours, wake at 6am, pack up, and head straight back to Hogwarts. It was a great introduction to a lifelong passion of being outdoors, fishing and walking the dogs.
