'Heroes' star writes 'Group Sex' movie

Heroes actor Greg Grunberg has started work on co-producing new movie Group Sex.

Grunberg partners with Alias director Lawrence Trilling in producing the romantic comedy about a single male who pretends to be a sexaholic to help attract his dream girl.

He also appears in the movie as the best friend of the male lead.

Josh Cooke and Odette Yustman star in the lead roles, while Desperate Housewives actor James Denton, Tom Arnold, Katherine Narducci and Happy Days star Henry Winkler are also in the cast.

Speaking about the movie, Grunberg told TV Guide: "This was a no-brainer. I had all of this free time and decided to get naked and laugh my ass off!

"I play Jerry, the best friend of the guy who follows the girl into the sexaholic meeting. Jerry is very critical of the girl his friend is fond of...maybe because he has a problem himself!"
