Short film with a guy on a phone in corridor trying to get money to save his life because he knows otherwise he will be killed and is killed eventually. It’s around the 70’s/80’s.
Another short film about a chick surviving being killed, apparently it’s famous.
This first one might be on this list: https://www.imdb.com/search/title/?title_type=short&release_date=1970-01-01,1990-12-31&plot=phone&sort=release_date,asc
