Synopsis by Hal Erickson
The Man Who Wouldn't Talk was coproduced by husband-and-wife Herbert Wilcox and Anna Neagle, with Ms. Neagle filling the role of Queen's Council representative Mary Randall. The title character is American scientist Frank Smith, played by Anthony Quayle, who is honeymooning in London with his new bride Eve Trent (Zsa Zsa Gabor). What the authorities don't know is that Frank and Eve are secret agents, bound and determined to pick up germ-warfare information from Hungarian scientist Horvad (Leonard Sachs). By prearranged agreeement, Smith will relay this information, and the purpose of his mission, to one man and one man only. His self-enforced silence proves to be a severe handicap when Eve is murdered and Smith is unable to provide an alibi for himself. It is up to lady lawyer Mary Randall to defend the close-mouthed Smith in court.
