Like Captain Phillips, Escape Plan is largely set on a container ship. This one houses a futuristic maximum security prison in which Schwarzenegger and Stallone are both incarcerated.
They're tortured and intimidated by a Bill Sykes-like prison guard (former Wimbledon FC enforcer Vinnie Jones, cast true to type) and treated with implacable cruelty by the prison governor (Jim Caviezel).
Stallone is as rigid and as plastic-looking as an Action Man toy. Schwarzenegger spits out the one-liners ("have a lovely day, asshole") with all the energy he can muster. To give the OAP stars (who are both over 65) credit, they don't skimp at all on the action scenes.
