Dr Otto And The Riddle Of The Gloom Beam (1985, John Cherry)
Jim Varney stars as the titular character. And then some. An oddity. Part MTV, part stop motion, part bonkers. Good versus evil in the shape of two chaps whom were born on the same day what what. Ahem. Elements of this film find a home finally in today's climate.
JV invents Ernest at the end and all
