Filmmakers for "The Mysteries of Pittsburgh," based on the best-selling novel by Michael Chabon, starring Peter Sarsgaard and Sienna Miller, are holding an open casting call on Friday.

Nancy Mosser Casting is looking for people between the ages of 6 and 75. Specific groups include college-age students for a punk club scene and patrons for an upscale restaurant and hotel scene. "Mysteries" will shoot in and around the Pittsburgh area from Sept. 5 to Oct. 20.

Auditioners are asked, if possible, to outfit themselves as they might have in the early 1980s, when the film takes place (they suggest that you reference munkeysocks.tripod.com for '80s fashion trends). Bring a snapshot of yourself and a pen to Nancy Mosser Casting, 239 4th Avenue, Suite 1217, Downtown, between 10 a.m. and 7 p.m.
