Robert Pattinson's strict time in a limo

Robert Pattinson says the script for Cosmopolis was "too good to pass up" after finishing with the Twilight film franchise and he had to stick to it.

Pattinson told the BBC's Tim Masters that director David Cronenberg gave some strict ground rules for filming - which involved sticking to the script.

The actor, who admits he is a Cronenberg fan, said he had challenges with preparing for the role because the script was so abstract.
