Lauren Ambrose, Cobie Smulders, Cedric the Entertainer and Tom Arnold come aboard writer-director Stephen Gyllenhaal's quirky Seattle-based political comedy, produced by Peggy Rajski

SEATTLE – Lauren Ambrose has joined the cast of the Stephen Gyllenhaal political comedy, GRASSROOTS, produced by Oscar-winner Peggy Rajski. Principal photography is under way in Seattle; Matthew Brady of MRB Productions is executive producing.

The screenplay is based on the Phil Campbell book, "Zioncheck for President," a memoir of the 2001 Seattle City Council election. Campbell, a recently fired reporter, signs on to run the campaign of his eccentric friend, fervent Monorail believer Grant Cogswell.

Ambrose, best known for her Emmy-nominated performance on HBO's popular, critically acclaimed dark comedy SIX FEET UNDER, will play Emily, Phil's girlfriend, a fellow journalist and Cogswell supporter.

Cobie Smulders, star of the long-running CBS series HOW I MET YOUR MOTHER, will play Clair, a Monorail supporter skeptical of the blundering Cogswell campaign.

Multi-talented renaissance man Cedric the Entertainer (LARRY CROWNE, BARBERSHOP, THE HONEYMOONERS) plays Cogswell's powerful political opponent, incumbent Councilman Richard McIver.

Versatile actor-comedian-sportscaster Tom Arnold (TRUE LIES, GARDENS OF THE NIGHT) picks up the role of Tommy, the sympathetic bartender whose club becomes the cash-strapped campaign's headquarters on election night.

Jason Biggs is already aboard as Phil Campbell, with Joel David Moore as Grant Cogswell.
