If you loved Otésanek - Little Otik, try Der Wahnsinn
Eine Brücke zwischen einem Film, den du schon gesehen hast, und einem, den kaum jemand kennt. Das teilen sie, und was der zweite macht, was der erste nicht macht.
Was sie teilen
Both films are directed by Jan Švankmajer, and they both carry the body horror, surreal mood tags, and they sit in Comedy / Horror territory. If that's the register that drew you to Otésanek - Little Otik, the second film will land in a comparable space — through a different lens.

What Der Wahnsinn is
Countryside road. Autumn wind. A gate creaks open. A young man seeks treatment at a bizarre sanitorium run by deranged pseudo-doctors. He soon finds himself prey to sadistic therapies and bizarre, carnal rituals. Švankmajer's live-action collage is not for all tastes.
