Nude Celebs: Bess Armstrong - Robert Louis Stevenson's horror classic takes a wildly comedic turn when scientist Daniel Jekyll (Mark Blankfield) discovers his inner Mr. Hyde -- who turns out to be a cheesy lounge lizard on the prowl. Packed with crass humor and sexual innuendo galore, director Jerry Belson's 1982 spoof also stars Bess Armstrong, Krista Errickson and Tim Thomerson. Watch for Cassandra Peterson (aka Elvira) in the role of a buxom nurse.
