David Croneberg, who directed Robert Pattinson in the upcoming 'Cosmopolis,' has compared Robert Pattinson to other "undervalued" actors like Keira Knightly and Viggo Mortensen.

The director told Hollywood Life that the young actor won't be able to realize his potential until he leaves Edward Cullen behind.

“It sort of pleases me to work with actors, like Rob, who have that potential, but haven’t had the chance to realize that yet and show it,” he said.

“I know [Rob's] big success is 'Twilight,' but as you know Viggo Mortensen‘s big success was 'Lord of the Rings,' but it didn’t show him at his most profound as an actor."

“I feel that … Keira Knightley is really quite undervalued and underestimated as an actress,” he said. “I think in A 'Dangerous Mind' [sic] she proves she is te superb level of actress she actually is. I’ve worked with some of the best, and she is up there; I feel the same way about Robert Pattinson."
