Matt Damon committed to directors

Matt Damon would "never sell" out a director.

The actor-and-screenwriter says once he has agreed to appear in a movie or has hired a filmmaker for the project he could never get rid of them, even if he didn't think it was working out, because he'd already committed to the project.

He told Men's Health magazine: "My movies being really good or watchable always depends on everybody being really good, not just me. I'm particularly sensitive about making sure we secure the best possible people in each role because I am not somebody who can overcome if we don't.

"And then, for me, once I make that commitment, I never will sell the director out on that project. You cannot change horses midrace. Even if your horse is losing, you ride the horse as hard and as fast as you can. If there was a mistake made, it was made in your initial decision to work with that person."

Matt - who is currently starring in thriller 'The Adjustment Bureau' alongside Emily Blunt - also revealed he and writing partner Ben Affleck never take offence when their ideas are criticised by the other person.

He said: "When one of us comes up with an absolutely f**king horrible idea, which happens all the time, the other person, without batting an eyelash, says 'That's a terrible idea.' And neither of us has our feelings hurt, and we just kind of move on."
