The movie (possibly a TV-movie, or even an episode on a show, but I think it is a movie) is in English, I’m thinking 80s or 90s.
The main character is a stock broker who is in some kind of trouble, and is approached by a girl who claims she is the devil (or working for the devil) and that she can help him if he sells his soul to the devil. The guy agrees. When she goes to report back to her “boss”, her “boss” is a homeless man (maybe blind) who asks her why she is pretending to be the devil instead of saying she is a guardian angel, and she tells him it’s because people tend to believe it more. Her homeless “boss” is actually God.
The movie ends with the stock broker loosing his house, and his colleagues buy it for him in an auction.
Anyone knows this movie?
