escape prison movie

0

hi everyone
i’m looking for a movie where the principal character is a prisoner and wants to escape.
i remember a scene where he let his shoes behind a sheet suspended front of wc in his cell. guard see the shoes sticking out of the end of the sheet and thinks that the prisoner is always sit on wc but he is already far escaping by a hole or something else. i think it’s an old movie like “escape from alcatraz”
thanks all
