cash on demand (1961)

AKA The Gold Inside.
"Its rather a good plan, don't you think?"
Fordyce (Peter Cushing) is a pedandic, bullying, and charmless bank manager, who comes up against a ruthless but superficially charming crook Hepburn (André Morell). Hepburn annouces that he has had Fordyce's wife and child abducted to ensure his total co-operation. But a flaw arises when the bank staff realise that something is not right and Fordyce has to beg them to keep quiet for his family's sake.
A claustrophobic little thriller well played by all concerned. For no apparent reason this was shown in 1961 in America, but the UK had to wait another two years to see this gem.

the trollenberg terror (1958)

AKA The Crawling Eye. Creature from Another World. The Creeping Eye. The Flying Eye. Trollenberg Horror.
"I believe that he was sent down the mountain with the express idea of killing Anne Pilgrim."
Anne and Sarah Pilgrim (Janet Munro and Jennifer Jayne) make the acquaintance of Alan Brooks (Forrest Tucker) on a train through the Swiss Alps. Anne insists that they get off at Trollenberg when it is announced as the next stop. By co-incidence Alan is also stopping there, to visit a friend, Prof Crevett (Warren Mitchell), who runs the local observatory. Anne soon starts talking about climbers who have gone missing recently on the mountain, she seems to know a lot about it for some reason, but how? Meanwhile Alan visits the Professor and he's soon told of the disappearances and a mysterious, radioactive cloud spotted moving around the mountain.
An enjoyable pulp sci-fi/horror, that makes the most of the small budget.
