I checked my Republic Pictures Home Entertainment VHS edition of DR. TERROR'S HOUSE OF HORRORS (1965) and it was released back in 1989! I believe that this Amicus Productions horror anthology film was originally theatrically released stateside by Paramount Pictures which may or may not still have copyright ownership. The Amicus Productions horror film THE SKULL (1965) is still under the ownership of Paramount and DR. TERROR'S HOUSE OF HORRORS (1965) may similarly find its way onto a DVD release via Legend Films. Of course this is all for the present just errant speculation. Jeff T.
