Bill Murray thinks actors are heroes.

The 'Ghostbusters' star - who recently had an entire day dedicated to him at Toronto Film Festival - claims people admire actors so much because they get to escape reality by pretending to be someone else.

He said: ''It's always a question, 'How are people pulling this off? How can they live with it, how can they be that person up on screen and then walk down a street or go to a grocery store or drive a car or have a conversation?' Like, 'How does that happen? Where do you get to be superhuman? How can you do it?'

''People identify with that. They think, I'd love to be Superman for a while, or be the guy who's being funny and not taking any guff. I wish I could say that to my neighbour or wife. That's what a hero does.''

The 64-year-old actor also spoke about his passion for road safety and claimed a movie should be made about politician Ralph Nadar, who made it compulsory by law to wear a seatbelt in 1965.

Bill told the Guardian newspaper: ''I mean, they made a movie about the German who smuggled the Jews out. He saved hundreds. Great man. Deserved a movie. Spectacular. Great film and a great human being. But this guy, Ralph - there's no movies about Ralph.''
