'Begin Again' Director John Carney SLAMS Keira Knightley's Acting

While out promoting his new film, Sing Street, director John Carney revealed his true feelings about Keira Knightly, who starred in his 2013 film, Begin Again.

In the film, Knightly played a songwriter, opposite Adam Levine and Mark Ruffalo, who both played musicians. "Mark Ruffalo is a fantastic actor and Adam Levine is a joy to work with and actually quite unpretentious and not a bit scared of exposing himself on camera and exploring who he is as an individual," Carney told The Independent. "I think that that's what you need as an actor; you need to not be afraid to find out who you really are when the camera's rolling. Keira's thing is to hide who you are and I don't think you can be an actor and do that."

Indeed, As RadarOnline.com reported, Knightley herself has joked in the past that her career is "all smoke and mirrors."

However, Carney did not stop there with his critique. "It's not like I hate the Hollywood thing, but I like to work with curious, proper film actors as opposed to movie stars," he admitted. "I don't want to rubbish Keira, but you know it's hard being a film actor and it requires a certain level of honesty and self-analysis that I don't think she's ready for yet and I certainly don't think she was ready for on that film."

The director made it clear that he was not aching to work with Knightley in the future. "I'll never make a film with supermodels again," he said. "Keira has an entourage that follow her everywhere so it's very hard to get any real work done, and so I was very ready to come back to Ireland and make films that nobody cared about who was in it or any of that crap."
