In a candid interview with The Guardian, Grint, now 30, revealed he struggled to separate himself from the character of Ron Weasley over the eight Harry Potter films.
Cast as Harry Potter’s best friend at age 12, Grint admitted he had only auditioned for the role because he was a fan of the J.K. Rowling novels.
But as filming wore on, Grint said shooting became a “massive sacrifice” and he resented having to work for long stretches at a time.
“I definitely remember thinking during one extended break, ‘This whole thing is so all consuming, do I really want to go back? Maybe it’s just not for me,’” he recalled. “I guess I was probably just being a teenager.”
Despite many child stars falling into partying at a young age, Grint said it wasn’t the case for the Harry Potter cast who “didn’t have the chance to discover drugs” filming in the UK.
But towards the end Grint said he and Ron became “virtually the same person” and adjusting to life after the last Harry Potter movie came out was difficult.
“There’s a lot of me in Ron and moving on was a massive adjustment because it was such a constant part of my life. I don’t want to liken it to coming out of prison because it wasn’t a prison, but it did feel like stepping out of an institution,” he said.
