What an actor is Donald Pleasance. His mesmerising, baleful pale eyes let the viewer see Crippen's every emotion while largely concealing his plans and motives. The film has a fine sense of 'period' and the end sequences are totally gripping. So did he or didn't he murder his wife? The movie leaves this open to some extent. Did something just go wrong when he gives his raucous wife Belle a dose of sedative to save himself from her horrid attentions? Study the sequence where the powder flies around: a slight head tilt, a hand movement, a tiny pause before resuming - acting at its finest.
Pleasance is more than matched by the wonderful Coral Browne whose faded music-hall singer is a courageous no-holds performance. She's appalling, vulgar, callous, needy and pitiable: she and Pleasance work wonderfully together. I'm less sure about Samantha Eggar as the virginal girlfriend, Crippen's love object. Unlike the other actors, she seems stuck in some sort of early Swinging London timewarp and with her there is little sense of period. She does though suggest quite nicely that Ms Neve is no yielding angel. When she reads Crippen the riot act - no nooky with Belle or else - it's clear that poor old Crippen has just bounced from one tough femme to another. Between them he is crushed, and accepts death with moving dignity. The dismemberment aspect, which might have put less glamorous light on his actions, is only fleetingly covered. The film is worth rewatching for its fine art direction, quiet lack of sensationalism and the brilliant performances of its two leads.
