Produced by Gene Roddenberry and directed by Clive Donner, 1977’s Spectre was a pilot film for a television series about an occult detective (Robert Culp) who solved supernatural mysteries while dealing with a curse that had been put on him by the demon, Asmodeus.
In this film, Culp’s William Sebastian and his associate, Dr. Ham Hamilton (Gig Young) travel to the UK to investigate a supernatural case involving an old family. Despite the efforts of a succubus and a cursed airplane, Sebastian and Ham are determined to solve the mystery. John Hurt appears as a member of the cursed family.
This pilot was not picked up and developed into a series but it was popular enough that it was released as a theatrical film in Europe.
