Hide And Seek (1963)

Cy Endfield directs this 1960s comedy thriller starring Ian Carmichael, Curd Jürgens and Janet Munro. Though Professor David Garrett (Carmichael) is very much on the West side of the Cold War divide - helping to develop a missile that could be used against the Soviet Union - an old friend of his is a Russian chess player and, through him, he comes to the attention of unscrupulous businessman Hubert Marek (Jürgens). Marek hatches a plan to kidnap Garrett and make it look like he's defected to the USSR and enlists the alluring Maggie (Munro) to entice the scientist into a trap.

Can Garrett keep his bearings and foil the malicious Marek?
