Enlarge By Jordin Althaus, Fox Searchlight Pictures Zooey Deschanel's bank teller and Joseph Gordon-Levitt's bank robber do a dreamy dance number in the highly stylized music video that sprang from their collaboration in (500) Days of Summer. Gordon-Levitt has a solo dance number in the film, which opens wide Friday.

What do you get if you cross Bonnie and Clyde with Fred and Ginger?

Zooey and Joe.

Their star-crossed romance in the comedy (500) Days of Summer has been making off with the box-office loot since its limited debut two weeks ago. To kick off Friday's nationwide release, Zooey Deschanel and Joseph Gordon-Levitt are giving away a separate short film, a music video about a bank heist in which the teller's heart is stolen along with the cash.

MAKING OF: Go behind the scenes

The video, directed by (500) Days filmmaker Marc Webb, premieres today exclusively at life.usatoday.com before moving to other TV and Internet outlets.

Gordon-Levitt plays a stoic man in a neat blue suit, turning to crime in a moment of absolute desperation. Deschanel is the gorgeous, wide-eyed teller, disarming the dangerous man (metaphorically speaking) in a playful, twirling, fox-trotting dance through the stuffy, starkly lit marble lobby. The other dour denizens go about their business unaware.

Deschanel and Gordon-Levitt say they hope to team up repeatedly and have aspirations of being a regular screen couple, like Fred Astaire and Ginger Rogers or Spencer Tracy and Katharine Hepburn.

They're not a real couple, but they're good at faking it.

"I think it's great to have continuous collaborators," Deschanel says. "It's a shortcut that makes it so much more fun. The job is much easier when you can go to set and be like, 'Ah, Joe!' "

"Absolutely. And there's trust," he says.

"And it's not like, 'Hey, nice to meet you — let's make out! LALAlalala," she says, closing her eyes and sticking out her tongue in a mock French kiss.

"As weird as it is filming a love story in front of a million people, at least you have your friend," she says.
