I can’t recall the theme of this movie but I recall this scene as it was so unusual. Its towards the end of this movie was a man kissing a blond woman, I think they were standing up naked, under a beam of bright light. He then takes a knife or sword and stabs her in the back and they both scream in pain. I keep thinking the guy reminds me of Bruce Willis but I can’t find a movie credit like this on his list.
Lifeforce. I enjoyed this and I was like 10, lol.
