Pandemonium (1987)

One night, a man in straitjacket, who seems to have escaped from an insane asylum, runs into a girl on a bench in the park and decides to tell her his life story. He was a young Egyptologist, who moved to an abandoned film studio turned boarding house. The place is owned by a horrid wheelchair-bound woman, who plans to sell it asap. Her tenants include one of Hitler's genetically engineered sons who's about to be inaugurated as the new Fuhrer, his evil incestuous lusty lesbian Nazi aunts, a voodoo zombie, a vampire scientist and other strange individuals. When a beautiful young naked virginal feral woman shows up in their seaside town of Babylon, Australia, chaos ensues. It turns out she'd been lost as a baby and was raised by dingoes but now she wants to meet her real family and the unhinged landlady is her mother. Mom is quite unpleasantly surprised by the arrival of the girl, since she purposefully left her to die in the wilderness for a very good reason and she tries to get rid of her. Everyone in the building becomes obsessed with the girl and has their own diabolical plans for her, even her mother's pervy husband, a failed filmmaker. The lesbian aunts plan to give the girl as bride to their spazzy Hitler jr. nephew, but others intervene to get her for themselves. Even her dingo stepbrother (played by a man in costume) shows up to have a bestial quickie with his loving stepsister and later her real supernatural father pops up as well to blow her mind and give her what she craves, which messes up the plans of several tenants, who need a virgin. Eventually, the Egyptologist realizes that the girl is actually the Second Coming of Christ and that only she can stop the upcoming apocalypse. However, the other tenants agree that the best way to help her do that is to crucify her, even though she vehemently disagrees. The ending surprises everyone, including the girl. Farcical slapstick supernatural dark sex comedy with a touch of Shakespeare spoof.
