The weirdest one I know of is Batman Returns. It had a budget of $50 Million in 1992, which would be about $117 Million in today’s dollars. Most of the imagery is deliberately offputting. The penguin murders children and shoves a whole dead fish into his mouth. Catwoman dresses in BDSM gear. Back when superhero movies were primarily for kids, Tim Burton made one that was not for kids.
Has anybody made a weirder movie at that scale?
