The Twilight star revealed that he would like to see more actors step "outside the box" when playing roles in franchise films, and praised Heath Ledger's performance in The Dark Knight as an example.
"I always thought after The Dark Knight... it makes tons and tons of money, and Heath is doing something just outside [the box]," ComicBookMovie quotes Pattinson as saying.
"People understand what he's doing, it's not like he's not doing something totally crazy, but it's just slightly outside the box of what people are used to seeing, and I really thought that was going to change everything about how the big budget movies are made.
"But it didn't, at all. If every single actor wasn't afraid of trying to do something slightly abstract and not concerned about their movie making tons and tons of money, then eventually the industry would change."

Asked whether he aspired to achieve that kind of iconic performance himself, he mused: "I think you can once. I don't know how many other times.
"I'm desperately trying to get a superhero movie now."
Pattinson, whose new film Cosmopolis premiered at Cannes last month, recently admitted that he has run out of creative steam with his role in the Twilight saga.
Cosmopolis opens in UK cinemas on June 15. Watch a trailer below:
