Howdy Larcia!!
Pard, I think the first scene you're referring to is from Sergio Leone's. The Good,The Bad And The Ugly with Clint Eastwood and Eli Wallach. Eli(Tuco) Wallach is in cahoots with Clint(Joe) Eastwood, who keeps turning in Tuco for the bounty and then shooting the rope in two when the townspeople attempt to hang him. Eastwood performs this stunt several times during the film and again in the final scene, when Tuco is standing on a wooden cross above a grave, with a rope around his neck.
The 2nd scene you are referring to is in The Last Hunt with Robert Taylor, Stewart Grainger and Debra Paget.
I don't recall ever seeing a film with the 3rd scene you refer to in it.
