The X Men star has developed a reputation as a good guy and he admits it's all thanks to Clooney.
He explains, ""I learned from the legend, George Clooney. I saw George Clooney at an event at the Waldorf Astoria, and, at any point, you think you may be in movies at some level, but the moment George Clooney moves in you realise you're not... He just got mobbed.
""He has this particular style... He gets, like, uncomfortably close, he gets in there and he never stops moving.
""You see people going for their phone because they want the autograph and they want the picture and they go for it... and before they've got their hand (out), he's gone and they're happy... It's just much quicker to be polite.""
