Dexter directed the above mentioned film and many others including "House Of The Damned", Hell's Belles" and "The Mini Skirt Mob".
He also helmed some episodes of "Little House On The Prairie" and "Father Murphy". I loved this man's movie work as most of the films were just plain odd. I proudly own the Hell's Belles poster.
Dexter passed away on May 28th at the age of 89.
