at the screening for distributors in 1983, Hell did come with the genius auteur who made it and nodded out at one point due to his heroin addiction. In between making the movie he got in a backstage brawl with Rockets Redglare which resulted in some broken ribs. (Look closely and you can see the bandages under his cowboy costume.)
Hell passed out on the set during some of the breaks too since he was self medicating with dope for the pain of the broken ribs. In spite of the injuries he gave what some consider his finest performance as the Rawhide Kid.
