Lost Highway (1997) IMDb
David Lynch (director).
Elusive. A 19-year-old whiz mechanic and all-around stud is substituted for an ageing, impotent and jealous avant-jazz sax player.
Psychogenic fugue. Really weird thriller and puzzler, quite a bit of erotica and violence. Great visuals, sounds, moods and mystery for mystery’s sake. Good humour, and some nice music (much of it is too mainstream on the other hand). Two people playing the main character who is two people is very nice. Fairly good answers can be found.
