Arnold Schwarzenegger to Join Sylvester Stallone in THE TOMB

It looks like there's a Aronld Schwarzenegger could end up co-starring along side Sylvester Stallone in a new action film called The Tomb. Schwarzenegger and Stallone recently worked together on The Expendables 2. The film is being developed over at Summit Entertainment, and Mikael Hafstrom (1408, The Rite) is currently in talks to direct the film. 

Schwarzenegger has only been approached to join the project so he's not officially locked in yet, but I don't see why he wouldn't do it. I don't think anyone has any issues seeing these two legendary action film stars working together again. Schwarzenegger was actually attached to play the character that Stallone is playing in the film years ago. Bruce Willis was also attached to the lead role at one point. 

The Tomb tells the story of a man (Stallone) who "has designed a high-tech prison that is said to be escape-proof. When he is set up and sent to the prison he created, he essentially must go up against himself to escape and find retribution." 

I've been hearing about The Tomb over the last few years, it sounds like it has a solid story that will make for a great movie, and I hope that it finally goes into production soon! I also love the fact that Schwarzenegger and Stallone could star in another movie together.  What do you all think?
