Jon Foster has been cast as Art Bechstein, the lead role in the film adaptation of Mysteries of Pittsburgh.

Foster (The Door in the Floor) will star along side Peter Sarsgaard, Sienna Miller and Mena Suvari, the Pittsburgh Post-Gazette reported Friday. The movie, directed by Rawson Thurber (Dodgeball) is set start filming in Pittsburgh after Labor Day.

Previously, Max Minghella (Art School Confidential) had been linked to Foster’s role, but had to turn the part down because filming conflicted with his college studies.

The film’s casting agency, Belajac Casting, is looking for “a very overweight actress, 20 to 25 years old, and a man in his 20s or 30s with a Mohawk haircut,” the paper reported.
