I don’t know but Escape Plan is like a spin-off of The Expendables starring Stallone and Schwarzenegger escaping the most secured prison in the world. It’s a story about a guy studying every prison and trying to find out guards weakness for them to strengthen the prison security. I like the idea of a glass cell and a prison in a cargo ship in the middle of the ocean. Its like doing research for prison facilities with them knowing this facility. It’s really an interesting movie and not too much action as the The Expendables but action scenes are great.
