Director Greg Mottola will start filming "Adventureland" in Pittsburgh on Oct. 3, and he is looking to fill several key roles with the help of Nancy Mosser Casting.

The agency is searching for someone to play Frigo, a 22-year-old childhood friend of the main character in the movie, who will be portrayed by Jesse Eisenberg ("The Squid and the Whale"), along with a teenage rock band that will perform a cover song from the 1980s, plus other speaking and extras roles.

Frigo is described as being as mature as an 11-year-old but having an innocence about his chronic childishness. He's envisioned as very skinny, almost "rat-like."

Mosser is looking for someone 18 to 22 with "incredible wild energy, who is naturally funny" and comfortable with R-rated language and crude physical comedy.

For Frigo, the band or other roles (roughly 1,000 extras will be needed, including men with longer hair reminiscent of 1987), contact Nancy Mosser Casting. Go to www.mossercasting.com where you can find an application or e-mail mossercasting@yahoo.com or call 412-434-1666.
