Robert Pattinson has blasted film age restrictions as ''crazy''.

The 'Twilight Saga' heartthrob claims adult movies shouldn't be subject to strict restrictions since most teenagers already have access to pornography on the internet, and thinks violence is more damaging than sex.

The 26 year old actor - who currently stars as a billionaire embarking upon a violence-ridden 24 hour Journey across Manhattan in David Cronenberg's 'Cosmopolis' - told The Sun newspaper: ''You're immediately in the highest rating with things to do with sex. But you can have violence. It's like, 'What?!' It's completely crazy.

''I don't think there's anything in 'Cosmopolis' that's particularly... there's nothing bad. I don't think there's anything that would have shocked me when I was 13. Especially when every single kid nowadays probably watches hardcore pornography on the internet. It's no worse - in fact, it's a lot better.''

Robert - who is dating Kristen Stewart - has a wild threesome in the film and shoots himself in the hand but he insists it's not as violent as people make out.

He said: ''I'm not worried about the violence or the sex or anything like that. 'Transformers' is more violent than 'Cosmopolis'.''

The British star recently disclosed that he didn't understand his new film, which is adapted from Don Delillo's novel, and was ''lost and confused'' on set.

He joked: ''David quite quickly realised that what he liked was when I didn't have any idea what I was doing, like I mean I was sort of sitting there, completely lost and confused, and he was like, 'That was the one!'''
