I don't know how to play a normal guy: Robert Pattinson

'Twilight' star Robert Pattinson does not know how to play a normal guy on-screen.

The 28-year-old actor thinks he doesn't know how to react normally to things in real life so playing a normal guy is difficult for him, reported Huffington Post.

"I want to do stuff that's unrelatable,I don't think I have particularly normal emotional reactions to things. So trying to play someone who is just a normal guy... I don't really know how to do it," Pattinson said.

Pattinson plays a simple-minded criminal who gets left for dead by his brother in his latest film, 'The Rover'.
