The currently director-less project, The Tomb has already signed Sylvester Stallone and is looking to bring on Arnold Schwarzenegger to play a key role. Antoine Fuqua was previously attached to direct.

Sylvester Stallone will still play the lead Ray Breslin. The film surrounds the expert prison designer who has to escape from the very structure that he helped create.

Both veteran action stars will soon come together for The Expendables 2 alongside Bruce Willis who was also interested in The Tomb's lead role, but passed.

The project is still in development.
