James McAvoy enjoys doing action scenes because he can get drunk the night before filming.

McAvoy insists physical moments and tricky stunts are not as difficult as portraying emotion so he feels more relaxed for those shoots.
Asked his biggest challenge, he said: "Not the action. Action is the bit where you go, 'Ahhhh great I can go on the p**s the night before.'
"As long as you jump from here to there and don't fall down in between, it's dead simple."
However, the 36-year-old actor hasn't always come away from his movies unscathed.
He said: "I was OK on this film ['Victor Frankenstein'] but I managed to punch the camera on my last job.
"I was f***ing dying mate. My whole hand swelled up and it looked like I was wearing a boxing glove."
McAvoy - who has a five-year-old son, Brendan, with wife Anne-Marie Duff - previously portrayed a depraved policeman in 'Filth' and admitted the role has attracted some "weird" offers from fans.
He admitted: "I've had a lot more offers of weird sex and stuff like that since doing the adaptation of Irvine Welsh's 'Filth'."
