I’m sure this film is 80’s or older. 70’s or even older most likely. Possibly b&w.
All I can remember is the ending. She is in the mans arms, embracing. He kisses her and a gunshot is heard. She slowly slips away from him and falls to the ground dead and the camera pulls up and away and the credits roll.
I believe they were dressed impeccably. Her in an evening gown and him in a tuxedo. He may have had a beard. It’s very fuzzy in my memory but I remember this film in my childhood and desperately want to see it again. I can’t recall WHY he shot her but I believe he had too. Perhaps she was going to kill him? If I could find this film that would be amazing!
Both versions of “I, the Jury” (1953 and 1982) end in a way similar to what you describe.
