Dir: Gordon Hessler
Starring: Alfred Marks and Vincent Price
A serial killer is on the loose in London and the Police follow him to a house owned by an eccentric scientist
This conspiracy thriller is acknowledged as one of the best science-fiction films made in Britain. Based on the 1967 novel The Disorientated Man by Peter Saxon, a house pseudonym used by various authors in the 1960s and 1970s, it features three peripheral railway scenes. First, there is a shot looking down onto the Mole Valley from Box Hill with a railway viaduct visible in the valley below. A near identical shot appeared in Nothing Venture (1948, qv). There is then a chase sequence on foot that includes Barnes station as part of its route, though no trains are seen, and a later car chase which crosses Betchworth level crossing, on the North Downs line in Surrey.
