Kristen Stewart is "fearless", according to Sopranos star James Gandolfini.
The pair worked together on the 2010 movie Welcome To The Rileys, and James reckons Kristen has even more to give as an actress.
Writing in Variety about Kristen's performance in the Jack Kerouac adaptation On The Road, James revealed the star is determined "to show (people) she is more than Bella in Twilight".
"As soon as she steps into the movie On The Road, you can't take your eyes off her. As Marylou, whenever she fixes her gaze, you see someone who will go as far as she can, and do it as mad as she can, to live and feel alive," he said.
"And it is sexy and scary and reckless and smart. She can play all of these things. She has them at her fingertips. She is just beginning. She is fearless.
"And that can be that good, and that can be very bad. But she is smart enough to handle it."
James - who has wrapped filming on the action drama Zero Dark Thirty - added: "There will be much, much more to come. Thinking about it, I am smiling already."
