Even these days it isn’t as easy to go crazy as you might think. Divorced Dr Miles Bennell (Kevin McCarthy) returns to his smalltown practice in California after being away for a couple of weeks at a medical conference. Seems like half the population has been complaining of a mysterious feeling and then not returning, claiming to be better. And the other half says family members aren’t themselves – they’re impostors, lacking nothing except emotion. When his ex Becky Driscoll (Dana Wynter) returns from England after her own failed marriage they visit mystery writer Jack Bellicec (King Donovan) and his wife Teddy (Carolyn Jones) because his double is lying on the billiards table and frankly it freaks them out. Becky’s father is a little strange too and as for the local psychiatrist…. Soon it appears the whole town is being taken over by alien seed pods now being actively cultivated to make everyone the same. Whether you take this as ‘straight’ sci fi or horror (as if that were ever a thing), a political allegory (it works for communism or fascism) or a warning about the homogeneity and groupthink of Fifties culture or even a comment on the brainwashing techniques used during the Korean War, this is brilliant cinema. From the sly innuendo of McCarthy getting back together with his ex, to the satirical thrusts at a humdrum life, this hasn’t aged a day. The scene when Teddy sees Jack’s double open his eyes while Jack is asleep is really thrilling. And as for the pods throbbing in the greenhouse! Adapted by Daniel Mainwaring from sci fi legend Jack Finney’s Colliers serial (later a novel) it was directed by Don Siegel. Whit Bisssell is the Dr in the concluding scenes and Sam Peckinpah plays Charlie the meter reader – he was director Siegel’s dialogue coach on this and four other of his Fifties films. The prologue and epilogue were added because the studio got cold feet over the pessimistic content – but you will never forget the sight of McCarthy shouting at the trucks on the highway, and this was its original ending. Nevertheless, this is extraordinary, urgent and fiercely exciting, simply one of the best films ever made.
