Arnold Schwarzenegger is his name, and action movies are his game. The former governor of California is set to star in a new prison-break thriller titled The Tomb with none other than Sylvester Stallone. Schwarzenegger will play an inmate, and Stallone has been cast as the designer of the prison. Shooting is expected to begin this spring in Louisiana. This isn’t the first time the pair has teamed up. Schwarzenegger had a cameo in Stallone’s The Expendables, a film about a team of elite mercenaries.
