Rossum, Lowell join ‘Light Years’

Indie drama stars Peter Gallagher

“Shameless” star Emmy Rossum and “Private Practice” alum Chris Lowell are in negotiations to join Peter Gallagher in the indie drama “Light Years.”

Maggie Kiley is directing from a script she co-wrote with Matthew Mullen.

Pic is a coming-of-age story based on Kiley’s 2009 short “Some Boys Don’t Leave,” which starred Jesse Eisenberg and won Kiley awards at the Tribeca and Palm Springs film fests.

Jason Potash is producing through his and Kiley’s What a World Prods. banner. Kyle Heller and Paul Finkel will also produce.

Production is scheduled to start at the end of May in Los Angeles.

Rossum is coming off the first season of Showtime’s series “Shameless,” while Lowell next stars as Emma Stone’s love interest in DreamWorks’ adaptation of “The Help.” Thesp was last seen on the bigscreen in “Up in the Air.”

Rossum is repped by ICM and the Schiff Co., while WME and Thruline Entertainment rep Lowell.

Gallagher is repped by Gersh and John Carrabino Management. Kiley is repped by APA and Zero Gravity Management.
