Is there another Żuławski film you'd recommend other than "Silver Globe" and "The Devil"? All I've seen is "Possession" and it's among my favorites so I've been meaning to check out for of his stuff (and the 2 on my list seem to be pretty highly rated).
I'm not expecting much outta "Phantasm" but sorta feel like it's something I need to see. Horror is the one film genre that I sorta have a weakness for in this regard. Maybe someday I'll learn my lesson.
Don't think I've ever heard anyone talk about "Sweet Movie" in real life (I'm guessing from your comment that is has a substantial cult following) but kept seeing it on RYM lists of "weird films" so I threw it on my "to watch" list. If it's something of a "stoner film", keep in mind that that's probably way more in line with my taste than yours.
