—MICHAEL STUHLBARG

What’s Helena Bonham Carter like on set? “When I first met her, she came into the makeup [room] and sat down and ate an enormous breakfast with fried eggs and sausages and fried bread. And I just thought, What a cool girl.” —EVE BEST (Stephen Lovekin/Getty Images for The Weinstein Company)

Colin Firth had to master a stammer in this movie. What’s the most difficult accent you’ve had to master for a role? “Actually, I related to it because I was terrified of singing in public for years because a nun had humiliated me in second grade.” Really?
