Saw this for the first time this week - then again the next day. Can't recommend this film enough and can't believe it's so overlooked. The original trailer is on Youtube but it's awful and does nothing to publicise the true gem this is. Fantastic cast - Hywell Bennett, Hayley Mills, Britt Ekland and a host of great British actors in minor roles such as Peter Bowles and George Sanders , haunting film score by Bernard Herrmann, every scene carefully shot with incredible use of colour - Wes Anderson eat your heart out - and a shockingly upsetting denouement which I never saw coming! Billed as a horror film it's not that conventional and is more of a surreal psycho thriller. Written by Agatha Christie but has far more of an eerie Daphne Du Maurier feel to it. A truly strange and unsettling film that will stay with you for days to come..
