Ray Breslin (Sylvester Stallone) is the world's foremost authority on structural security -- specifically prisons. His skills are put to the test when he is framed and put in a high-security prison of his own design and must find the person who put him there. Miles Chapman wrote the action screenplay, with Jason Keller providing a rewrite.
They also noted the following:
Sylvester Stallone is breathing life into "The Tomb" for Summit and Emmett/Furla Films.The two companies have been trying to get the pic off the ground for some time, and the project has seen a revolving door of action vets come and go. Antoine Fuqua was once attached to direct and Bruce Willis originally positioned to star. After Willis moved on, Arnold Schwarzenegger considered the pic for his post-politics big screen return.Schwarzenegger instead chose Lionsgate's "Last Stand" and Fuqua moved on to direct "Southpaw" for MGM, leaving "The Tomb" in a holding pattern.
The Tomb will most likely be Sly's next project after Expendables 2. Sounds awesome to me, what do you guys think?
