You may recognize the sexy trio backing up blue-eyed indie-cutie Zooey Deschanel in this December's Jim Carrey comedy "Yes Man". It's San Francisco's own, Von Iva making their big screen debut and singing along Ms. Zooey in the fictional band Munchausen by Proxy. Von Iva also wrote the song "Yes Man" specifically for the film (it'll run over the end credits). This isn't the first time the ladies have contributed to a Hollywood production (see Showtime's The L Word or the 2008 Jerry O'Connell/Heather Graham movie Baby on Board), but it is the first time you can see them rocking the big screen. The film comes out December 19th.
