"Our scenes include daytime exterior dialogue with precision driving and special effects. Our special effects include but are not limited to gunfire, sparks, squib hits, smoke, debris, air mortars and controlled pyrotechnic blasts," the movie's location managers wrote, in five pages of details about various street closures and other restrictions.
When the filming begins on Aug. 10 on Oliver Avenue, there won't be any pyrotechnics, they said, but "we will be covering Oliver Ave. and Smithfield St. with snow."
The set moves to Cherry Way on Aug. 12; Smithfield Street on Aug. 13 and 14; Smithfield, Third Avenue, Wood Street and Fourth Avenue on Aug. 17 and 18; and Strawberry Way, Seventh Avenue and William Penn Place on Aug. 20. The last traffic restriction is scheduled to be lifted at 10 p.m. Aug. 21.
Parts of Forbes, Oliver, Third, Fourth, Fifth, Sixth and Seventh avenues, Smithfield and Wood streets, William Penn Place and Cherry and Strawberry ways will be closed at various times. On-street parking will be restricted, as will access to some garages. Police will have to stop traffic for brief periods."
