Ethan Hawke has admitted he has had to get "super Zen" about criticism of his performance as Macbeth.
The Hollywood star is playing the Shakespearean character on Broadway and his performance has had mixed reviews, with USA Today saying he "lacks certain fundamentals necessary" and The New York Times suggesting "he delivers Shakespeare's poetry like a moody, glue-sniffing teenager reciting Leonard Cohen lyrics to himself".
Ethan - who also had a stage role in Henry IV in 2003 - admitted he does "care immensely" about the critical reaction.
But he added: "I don't control it and I have to get super Zen about it.
"I can't allow anyone writing about the theatre to take away from me whether or not this is a good idea to do."
The actor, 43, revealed he is always up for trying something outside of his comfort zone.
"I've been learning on my feet in front of people since I was 18," he said. "Early on I realised that if I was scared of failure, I wasn't going to learn anything."
Ethan also revealed that, unlike many other actors, he didn't avoid watching other people play the role.
"I decided, 'I'm going to watch 'em all'," he said, explaining he immersed himself in performances by actors including Nicol Williamson, Sir Sean Connery and Sir Ian McKellen. He said: "All summer I did this. I thought if I had one in my head too much I might imitate it. So I inundated myself with it. I can't even remember what anybody did."
