The fan screening will take place at the Reading Cinemas Gaslamp 15 on Thursday, July 18.

Convention attendees can get their tickets for the screening through online giveaways, at the Summit Booth on the convention floor and via a giveaway outside the screening location on the evening of the event, while supplies last.

Escape Plan follows a structural engineer (Stallone) who is wrongly convicted of a crime and sent to a maximum security prison of his own design. There, with the help of a fellow prisoner (Schwarzenegger), he plans a daring escape from the high-tech jail. Directed by Swedish filmmaker Mikael Håfström, Escape Plan hits theaters Oct. 18 via Summit Entertainment.
