Trivia, insights & behind the scenes
John Fowles hated this adaptation so much he allegedly walked out of the premiere. The studio cut 20 minutes without director Guy Green's approval, making the already confusing plot nearly incoherent.
This flopped so hard it basically killed the 'intellectual psychedelic mystery' genre until The Wicker Man arrived to salvage island-based psychological horror. Even Caine and Bergen disown it.
