One of the strangest yet weirdly satisfying films I've ever come across, Funky Forest also seems like the one that gets aliens right, somehow. They're going to be incomprehensible, bizarre, probably kind of gross, and our reactions to them are going to be likewise. Bonus points for a lot of catchy tunes and a sort of inside-out interrogation of Notice Me Sendai.
A perennial favorite Ken Russell spectacle, outlandish, artificial and sensational, depicting an equally bugnuts event from actual history. Oliver Reed at his 1970s peak, and an unforgettable performance
by Vanessa Redgrave, picking bits of scenery out of her teeth at the end of every scene. Decadent AF, but with a sad and serious point about love, religion, and politics don't belong together. An underrated gem.
