How much did Barker have to do with the Hellraiser sequels?
Not much. He sold his rights to Hellraiser for $1 million in the deal that allowed him to direct the first film. Hellraiser 2: Hellbound, while based on a story by Barker, was directed by Tony Randall. Although he was listed as “Executive Producer” of the films, he had no creative input in making Hellraiser 3: Hell on Earth, which was directed by Tony Hickox; or Hellraiser: Bloodline, which was directed by Kevin Yagher, but released under the name “Alan Smithee” because Yagher was dissatisfied with the studio’s edit of the film; or in the forthcoming Hellraiser: Inferno.
