You can change a person's life in an instant; put him in a movie, and you start thinking differently, you want to be in another movie. It's like an addiction almost.
Now let me say that Matt Busby was a great manager and Manchester United wouldn't be where they are without him. He was a god at the club, but he wasn't a god to me. Football is like that sometimes.
To act with a tennis ball and imagine it's a tentacle, or if you're in some kind of wilderness film and you go, 'Okay, we can't have a grizzly bear here, but imagine when you step over the rock there there's a grizzly bear.' I don't know. They're tough moments.
