Producer Mark Canton, who is lending his skill-base to the new Schwarzenegger-Stallone prison flick “The Tomb”, revealed on the ol’ wireless that Jim Caviezel has been cast in the film.

Caviezel, currently seen on TV’s “Persons of Interest” but known for such flicks as “The Passion of the Christ” and “Frequency”, would play the Prison Warden in the actioner, which sees prison designer Stallone having to escape – with the help of fellow inmate Schwarzenegger – one of the prisons he designed.

Canton (“300″) revealed the casting on The Matthew Aaron Show, noting that Caviezel had only been signed 24-hours before.

The prolific producer is giddy with excitement about teaming the action icons, saying though “The Expendables is fantastic” it’s great to have Stallone and Schwarzenegger going “mono e mono… like in Heat… or a movie of that quality.”

Mikael Hafstrom directs “The Tomb”.
