The Fifth Floor (1978) – Howard Avedis.

After ingesting poison, dishy disco dolly Kelly suffers seizures and is sent to a hospital for psychiatric evaluation. During her increasingly horrific stay in this generously choc-fulla-nuts psych ward, this sweet, kindly young lady is subjected to unspeakable torments at the mucky mitts of a monstrously sleazy orderly (Bo Hopkins). Avedis's Loopy Lou thriller The Fifth Floor is both earnest, wildly exploitative and deliciously unhinged, yet the mostly credible performances only just barely keep it north of utter bosh. The hyperactive, rubber-faced Robert Englund appears to be auditioning for a guest spot on Saturday Night Live, yet it is these divinely distracting lapses into unfiltered absurdity that makes it all so terribly irresistible! The Fifth Floor's squirrelly admixture of lurid W.I.P tropes, ribald Disco digressions, and rampantly Nut Hatched eccentricity strongly suggests a brand new movie cult in the making. When my time inevitably arrives, I shall openly admit that I'm hopelessly insane, since, according to trenchant Hollywood lore, to zealously claim your sanity is to guarantee another 90 days in stir!
