Hollywood has assembled a cast so manly it's already gotten half its audience pregnant and we're not even talking about an "Expendables" sequel.

Variety reports that Sylvester Stallone and Arnold Schwarzenegger's upcoming thriller "The Tomb" has assembled a motley crew of big-name stars, including Curtis "50 Cent" Jackson.

The film tells the story of a security expert (Stallone) who finds himself locked up for a crime he hasn't committed in one of the high-security prisons he designed. He must call upon a very special set of skills – likely a combination of civil engineering and ass-kicking – to free himself and prove his innocence.

While Fiddy has not yet announced what his role in the film will be, one thing's for sure: with seven movies scheduled for release in 2012 and 2013, he's come a long way from his days extolling the virtues of faking birthdays, taking ecstasy and getting rubbed.

Vincent D'Onofrio, Vinnie Jones, Jim Caviezel and Amy Ryan round out the"Tomb" cast additions.

Ryan, who's spent the last decade transitioning between movie roles, like her Oscar-nominated turn in "Gone Baby Gone," and high-profile TV parts on "The Office" and "The Wire," will play Stallone's business partner with whom he may be romantically linked.

D'Onofrio, who's spent much of his post "Law & Order" time on the other side of the camera, is in talks to play the prison bureaucrat who convinces Stallone to take on one last assignment. Jones, as usual, will play a terrifying bad guy.

"The Tomb" hits theaters in 2013.
