Alex O'Loughlin and Odette Yustman K-I-S-S-I-N-G ... for 8 hours

Odette Yustman knows what it's like to kiss Alex O'Loughlin for hours on end.

Before their paths to stardom caught fire, the "You Again" and "Cloverfield" actress -- who starts a series run when FOX debuts the security-firm sitcom "Breaking In" Wednesday, April 6 -- locked lips with the current star of CBS' "Hawaii Five-0" reboot in the opening scene of "The Holiday," the 2006 romantic-comedy movie in which Jack Black plays a composer who matches his music to footage of them.

"It's so funny," Yustman tells Zap2it. "In this business, you get asked to do certain things, and you do a lot of it to have contact with some big names and just get experience. I remember my agent calling and saying, 'There's this small part at the start of the movie, and (writer-director) Nancy Meyers would love to meet you.' And I thought, 'How can I pass that up? Absolutely!'

"I met her, then I ended up having to kiss this guy for hours! It was a tricky shot because you had to get the angle right, so it was very specific; I'd say we were there for a good eight hours, at least. We were troupers, though. I was in good company, and it was just a fun little thing. It's one of those things you do when you're just starting out."
