The Snatch star tells The Sun, "I might have a film coming up with Arnold Schwarzenegger and Sly Stallone. Those boys are knocking on a bit (getting older). At least I'll be prepared if the action scenes get a bit too heavy for them."

Cast Announced for Schwarzenegger/Stallone Thriller The Tomb

Vincent D'Onofrio, Vinnie Jones, Amy Ryan and 50 Cent have joined the cast of director Mikael Håfström's The Tomb, Variety reports. They join the previously-attached Arnold Schwarzenegger, Sylvester Stallone and Jim Caviezel.

The film follows Ray Breslin (Stallone) who is the world's foremost authority on structural security. He’s analyzed every high security prison and has gained a vast array of survival skills. But all Ray’s ingenuity and knowledge are about to be put to work in the most challenging test he's ever faced: escaping from the master prison of his own design.

D'Onofrio (Chronicle, "Law & Order: Criminal Intent") will play a deputy director, Jones (Snatch) a prison guard and Ryan (Win Win, "The Wire"), Breslin's business partner. There's no word yet on who 50 Cent (Get Rich or Die Tryin') will be playing.
