The "American Success Company" (AKA "Good as Gold" or "The Ringer"). It was later re-edited slightly and titled "American Success". Then it was re-edited again with many scenes switched around, a couple scenes added, and a narration by Jeff Bridges added and titled "Success".
I'm not sure why it was re-edited twice, but I think the reason might be related to the reason it was never released on video (except for a few copies when it was re-titled "Good As Gold") in the U.S.
It's a somewhat humorous story about a guy (Bridges) who's considered by his boss (Beatty) and his bosses daughter, who's also his wife (Bauer), to be a loser. So, with some makeup, some exercise, and some help from a local prostitute (Jagger) he becomes a new man. He also conceives a plan to steal a lot of money from the company that he works for (AM-SUC-CO, a movie version of American Express).
The last version ("Success") has a narration by Jeff Bridges, which clears up a lot of plot holes and confusion that are in the first two versions of the movie. Plus, I liked the extra scenes in the last version, which aren't in the previous two versions. "Success" is the version to see if you can find it.
