Actor Ralph Fiennes called on his dialect coach to help him with his directorial debut - because he knew she'd be honest about his performance in his film Coriolanus.
The English Patient star admits he was wracked with "continual anxiety" when filming started on the movie adaptation of the Shakespeare tragedy - because he couldn't be sure he was giving the best performance in front of the camera as he attempted to direct himself.
So he called on his friend and coach Joan Washington to help him.
He tells WENN, "I couldn't tell if I was delivering it. I very much relied on Joan Washington, who is admired as a dialogue coach in the U.K., and I brought her on the set to oversee the speaking of the Shakespearean text for everyone.
"She also became my own acting coach and gave me honest critical feedback on my performance."
