New Line woos duo for 'Valentine's Day'

Abby Kohn, Marc Silverstein to pen romantic comedy

New Line is just that into Abby Kohn and Marc Silverstein.

The studio has signed the duo to pen "Valentine's Day," a love story revolving around five relationships in Los Angeles, all of which are put through the paces during the course of one Feb. 14.

"On Valentine's Day there's so much more pressure on a relationship," producer Mike Karz said. "A lot of the movie is about how that increases the tension." The relationships will run the age gamut, Karz said.

The CAA-repped Kohn and Silverstein recently penned the ensemble romantic comedy "He's Just Not That Into You," the New Line pic based on Greg Behrendt and Liz Tuccillo's best-seller which opens this weekend.

Garry Marshall is attached to direct "Day," while Karz and Wayne Rice are on board to produce the film, which is based on an original script by Katherine Fugate. Josie Rosen is exec producing, and Sam Brown and Mike Disco are overseeing for New Line.

Marshall added that honing the characters will distinguish this movie from other romantic comedies.

"A lot of people put in a few big jokes and two more blocked scenes," he said. "What these two (writers) do is character delineation. Aristotle wrote it in 300 B.C. and it's still true today -- 'You've got to have character.' "

New Line has not officially greenlighted "Day," but if things move forward, it could shoot this year for a potential Valentine's Day 2010 release.

New Line has strong enthusiasm for Kohn and Silverstein. The writing duo is also attached to pen "How to be Single," a story of a group of single women based on the novel by former "Sex and the City" writer Tuccillo.
