William Mapother, Illeana Douglas, Bubba Lewis and Greg Grunberg are toplining indie drama “It’s Dark Here” with shooting starting Monday in Los Angeles.

“It’s Dark Here” is being produced by Jonathan M. Black (“She Wants Me”) of Cinipix, which recently wrapped production on “Raze,” starring Zoë Bell and Rachel Nichols.

Adam Coplan, a former executive for Scott Rudin and John Davis and a co-producer of “The Express,” is making his directorial debut and directing from his own script.

Based on a true story, the film follows a 20-year-old college student and musician Jason Tennies (portrayed by Lewis) who suffers an apparent schizophrenic break and plunges his family’s lives into sudden tragedy. Douglas and Mapother will play his parents as they seek answers and medical treatment before it’s too late.

Tennies passed away in 2010 after being struck by a car. A portion of proceeds will benefit The Jason Tennies Memorial Foundation, founded to raise funds and awareness of schizophrenia, bipolar disorder, depression and autism.

Production is set to wrap mid-November.

Mapother and Douglas are repped by Don Buchwald & Associates/Fortitude. Lewis is repped by Innovative Artists.
