Trivia, insights & behind the scenes
Britt Ekland filmed this between 'Get Carter' and 'The Wicker Man' — her 1972 was impeccably chaotic. The glass house was a real building near Torremolinos, Spain.
Agatha Christie reportedly hated this adaptation of her 1967 novel, possibly because it leans harder into Michael's erotic obsession with wealth than her original. The film's flop helped kill the 'Christie psychosexual thriller' subgenre she'd accidentally spawned.
