The 34-year-old actor is now a huge global star thanks to his roles in films such as 'A Dangerous Method' and 'Shame' and while he used to be upset at not winning roles when he was younger, he is now grateful for it.
He said: "You know, I spent a lot of time out of work. Now I'm trying to make hay while the sun is shining. I wouldn't change anything. The fame thing, the honey traps, I don't know that I would've handled it well at 23. I would've gone ape sh*t."
Despite being a huge star now, Michael is still very grounded, which he credits to his upbringing in rural Ireland.
He told Now magazine: "My upbringing was pretty innocent. Fishing, climbing trees and running around the countryside.
"I was also an altar boy at a local Catholic church responsible for unlocking the doors in the morning. I slept in a few times. The whole congregation would be waiting outside and I's be running across the fields with the keys."
