It sounds a bit like “Until the End of the World” (1991) but all jumbled up.
It also feels a bit like “Mulholland Drive” (2001)
After Hours (1985) has a similar vibe
None of these are total fit but they are all good movies so what have you got to lose?I’ve only seen Mulholland Drive but it’s the opposite of a good movie.
Greatness can sometimes be the opposite of good. We don’t remember Herod as Good or Alexander.
