Hair today, gone tomorrow: Robert Pattinson slicks down his famous big barnet for new city boy film role

He is almost as famous for his big tousled mane of hair as for his acting roles. 

But Robert Pattinson may disappoint fans of his distinctive hairstyle by slicking it down for a new film role.

Decked out in a smart suit, with his famous barnet plastered down into a side parting, the British actor looked a far cry from his role of Twilight vampire Edward Cullen as he filmed Cosmopolis in Toronto earlier today.
