 One of the inmates of the Matamoros High Security Prision, known as  Tun Tun, was helped by the cast and crew of the film to obtain his  freedom. Tun Tun, a small man that appears in the film as one of  Germans bodyguards in prison, was in jail because he tried to steal  a bike and was unable to pay the fee. The cast and crew created a  found named "Free Tun Tun" and everyone gives 5 dollars to complete  the fee. Tun Tun was released the final day of shooting in the  prison. He didnt expect it.
