Might be called "Sally Bowles Comes Home And Runs Liquor." Her character is almost a parody of her "Cabaret" role. Hackman is Buck Barrow with a comedy twist and Reynolds is perfecting that moron-suave character that he took to such heights in "At Long Last Love."
The film has the distinction of having had, if memory serves, three different endings. I saw the first in previews. A real curve ball in which the male leads get killed and Minelli is left bereft. They went back to the drawing board and the movie premiered with a tacked on scene shot much later which involved the three stars, with the tackiest of make-up jobs, rolling around in a bed in their "elderly" years. From what I can tell by watching it recently, they dropped that entirely and simply cut together some outtakes which they ran under the credits which give us the impression that everybody ended up okay.
There was also this mid-70's technique of film "flashing" which involved pre-exposing the stock to give the film a lighter, airier look. Taken to ridiculous extremes here, it almost looks as if someone just scratched up the lens faces with a Brillo pad.
