The 25-year-old actor, whose latest film on the impact of an economic collapse on the people across the globe is a departure from his hit Vampire franchise, said he tries doing different films but cannot assure their success, reported Contactmusic.
"I'm curious to know whether people who liked the 'Twilight' movies will come and see things like 'The Rover'.
Hopefully they'll enjoy it. I try to do ambitious projects but I don't know if people are going to like them. You just try to do things which are challenging and hopefully people will appreciate that," he said.
Robert Pattinson plays the role of Ray, a slow-witted character who is a lost soul in 'The Rover', which releases in the UK on August 15.
