The film was released on November 1, 1972 by United Artists as a double feature with Superbeast.
The address number of the antique shop, Treasures of the Orient, where James Robertson buys the painting, is 666.
The address on the collar of the dog Nicodemus starts with 666.
Just after James Robertson is chased from the antique shop, Treasures of the Orient, a poster for the James Bond film You Only Live Twice (1967) can be glimpsed for the briefest of moments on an exterior wall.
Much of this film's story line is similar to the one Tom Selleck had later in the TV series Magnum P.I., such as the story taking place in a tropical setting and the main character driving a sports car and getting chased by a dog.
