Ethan Hawke is out and about in New York, the city he's lived in for 30 years, a place where famous faces slide past every day. He's wearing a baseball cap, a hoodie and a pair of cords. It's an outfit you might think he chose especially to look nondescript, but in reality it's because he likes corduroy trousers, though his stylist hates them and wishes to God he wouldn't wear them in public.

Someone spots him and timidly approaches. As they lean forward Hawke can see the tears in their eyes. The fan trembles: "Mr. ... Dorff?" Hawke doesn't want to ruin their moment, so he gives a smile, shakes their hand. This has happened before — Ethan Hawke gets mistaken for a lot of famous people. Christian Bale, Sean Penn, Brad Pitt. And, it seems, Stephen Dorff.

"You start realizing how many fans Stephen Dorff has," laughs Hawke as he tells the story. "Wow, people really love him."
