Domhnall Gleeson on his awful first day on the set of Harry Potter

We didn't expect this.

Domhnall Gleeson has spoken out about the pressures of working on Harry Potter. Speaking to The Independent, the actor said that he was a bit starstruck on the first day of shooting The Deathly Hallows, and even mixed up his accent. "I was a Harry Potter fan, but on my first day on set on Deathly Hallows, I had a horrible day, just a terrible day. "There were 300 people on the set, it was absolutely nuts, I went Australian on the accent instead of English, I kind of panicked, you know, I met these amazing people whose work I had watched and loved for years, and the pressure got to me. "I didn't handle it well, the first day, but after that I got better, and I learnt that I'm going to be under similar pressure in the future but I'm not going to let it get to me." We loved Domhnall in The Deathly Hallows so it's a surprise to hear he was so nervous! The Irishman is currently promoting his new movie, American Made, which he stars alongside Tom Cruise. It is set in the 1980s and tells the true story of Barry Seal, an airline pilot who smuggled cocaine into America for the Medellin cartel while also acting as a mole for the CIA.
