It played much of the U.S. under this title and was still being shown as late as October 1987.
The film gives higher screen credit to Britt Ekland, who had only a minor role but more star power, having previously played Mary Goodnight in The Man with the Golden Gun. Lana Wood is known to many as Plenty O'Toole from the James Bond film Diamonds Are Forever. Kabir Bedi was featured as the Bond villain's henchman Gobinda in Octopussy.
For the scene where The Spirit awakens a naked, sleeping Lisa using his demonic powers to pull the sheet off her, a wire was attached to the sheet to pull it off of actress Lana Wood while she laid in the bed naked.
