Arnold Schwarzenegger and Sylvester Stallone shared the screen in two Expendables flicks, but here they both take lead roles. Stallone plays a prison expert who’s locked up in a high-tech facility of his own design; Schwarzenegger is a mysterious fellow inmate. The escape plan somehow involves a confrontation between the action icons (and sometime Planet Hollywood investors). ”It felt really important to have a fight,” director Mikael Håfström says. ”We grew up with these guys. You can’t make a film with Arnold and Sly and not give them that kind of moment.” To translate so your 12-year-old self will understand: This is the movie where Rambo punches the Terminator.
