The prison escape drama The Tomb has quite the casting history. Bruce Willis was initially set to star in the film for director Antoine Fuqua, but eventually dropped out. After Willis left the project, Arnold Schwarzenegger was considering it as a possible comeback film. When Schwarzenegger chose The Last Stand as his post-Governator pic, Sylvester Stallone signed on to star as Ray Breslin, an authority on high security prisons who is framed and incarcerated in a master prison that he designed himself. In a serendipitous development, sources now tell Harry over at AICN that Schwarzenegger is actually circling and discussing with Stallone the possibility of coming onboard in a different role.The plot concerns Stallone’s character trying to escape the prison, so Schwarzenegger could possibly play a fellow inmate or the man who put Stallone in prison in the first place. Either way, this 80s action star team-up is quite the intriguing prospect. The film is currently without a director, but if Schwarzenegger does indeed sign on Summit will likely want to get things moving quickly. The Governator is set to move on to the supernatural actioner Black Sands after he wraps The Last Stand.
