Sylvester Stallone and Arnold Schwarzenegger team up for an implausible — but straight-ahead — action-adventure about a security expert (Stallone) whose all-consuming job is breaking out of maximum security facilities — on the government’s dime, of course — to test the weaknesses and flaws in the construction and guarding of prisons. When he’s hired to break out of an ultra-secret, high-tech prison called “The Tomb,” he’s deceived and betrayed and finds himself a prisoner in an escape-proof facility. He’s forced to team up with another inmate, an international criminal (Schwarzenegger), to help devise a daring, nearly impossible plan to escape. It’s great to see these muscle-bound stars still in action — Stallone is 67, Schwarzenegger 66 — but their stamina kind of belies reality: they’re fighting and beating up guys a third their age. Oh well, if you can overlook that, then you’re in for a fun ride.Extras: Commentary with director Mikael Hafstrom and co-writer Miles Chapman, “Executing the Plan: The Making of Escape Plan” featurette.
