Two Jake Gyllenhaals — for the Price of One!

In the new film Enemy, Jake Gyllenhaal finally meets his match, playing a college prof obsessed with an actor with the good looks and quiet intensity of... Jake Gyllenhaal! But he's not the first star to confront his freaky double. Here, four more.

DOMINIC COOPER
The Devil's Double (2011)

Dom stars as both Uday Hussein and the poor guy commissioned to undergo plastic surgery to look like Uday Hussein. Hot. OK, sick. But hot!

NATALIE PORTMAN
Black Swan (2010)

Portman wasn't just chasing an Oscar in this ballet potboiler. She was chasing after a creepy-ass copy of herself. Or was she? Yay for paranoid primas!

EWAN MCGREGOR
The Island (2005)

In which he plays a rich car designer and his clone. And, for once, doesn't get naked -- as either! Booooo.

DREW BARRYMORE
Doppelganger (1993)

Teen Drew didn't work much, but she did show up in this turd about a per- fectly nice young lady tormented by her equally apple-cheeked alter ego. Stinky!
