Rod Cameron, Lois Maxwell and Clifford Evans star in the 1956 British second feature mystery thriller Passport to Treason, in which a private eye investigates a world peace group that is a front for a crime syndicate.

Director Robert S Baker’s 1956 second feature crime film Passport to Treason is based on the novel by Manning O’Brine, and stars Rod Cameron, Lois Maxwell, Clifford Evans, and John Colicos.
Rugged Canadian star Rod Cameron came to Britain for producers Robert S Baker- Monty Berman’s fair mystery thriller about an American private detective, Mike O’Kelly (Cameron), who tries to solve his friend and colleague’s murder.
Lois Maxwell (aka the Bond series’s original Miss Moneypenny) plays Diane Boyd, an MI5 agent who helps him pursue the trail to a crime syndicate group of fascists hiding behind the guise of being a peace organisation.
Passport to Treason is a familiar but acceptable and mildly entertaining Fifties B-movie, with a competent screenplay by Kenneth R Hales and Carry On film writer Norman Hudis from the novel by Manning O’Brine.
