ACTION film heavyweights Sylvester Stallone and Arnold Schwarzenegger are shown looking pensive and ready for action in the first official still from their new movie The Tomb.

Arnie and Sly have already blasted back onto the big screen in full throttle guns and glory sequel The Expendables 2, but the duo clearly can’t get enough of working together.

The official photo revealed in The Wall Street Journal shows both the actors in character, standing in what appears to be a prison wearing matching inmate uniforms and looking off into the distance. Meanwhile, other prisoners mill about behind them.

The Tomb follows Stallone’s Ray Breslin, a security expert with knowledge of high-security prisons. After he gets framed by some unsavoury types, Breslin has to escape from one of the prisons he helped to create.

Total Recall star Schwarzenegger plays Emil Rottmayer, an inmate who befriends Breslin who isn’t all he seems - which could explain Arnie’s dubious facial hair.

In a video interview with Entertainment Tonight, Stallone described the film as ‘pretty extraordinary’.                  –Metro
