need the name of a movie. Please help?

I once saw a movie on tv. i have a blurred memory of it. a bunch of people trapped somewhere , like on an island where people have gone missing. on the island there are traps. one of the traps r electric water that i guy in a wheelchair have to avoid climbing in pipes over the water. another thing is an extremly cold gas that freezes a guys leg into the bone , and then the legs cracks and he's laying on the ground without legs. another thing i remember is that the remaining people finds a room with a body hanging i ropes that is controlled.

anyone know the name of this movie?
