3 from Gilliam? Agreed, tho Might as well just watch everything he’s associated with.

Fisher King & Time Bandits are lovely. Zero Theorem, the Man Who Killed Don Quixote, Imaginarium of Doctor Parnassus, Adventures of Baron Munchausen.

All the Monty Python, of course.

Clockwork Orange was pivotal in my late teens, early twenties.

Eraserhead as well, other Lynch works: Blue Velvet, Twin Peaks & Lost Highway hold solid ground for me.
