From the real life experiences of Matt Cvetic [published in the Saturday Evening Post as I Posed as a Communist for the F.B.I], scripter Crane Wilbur has fashioned an exciting film. Direction of Gordon Douglas plays up suspense and pace strongly, and the cast, headed by Frank Lovejoy in the title role, punches over the expose of the Communist menace.
Cvetic’s story is that of a man who, for nine years, was a member of the Commie party so he could gather information for the FBI. His informer role was made all the harder because his patriotic brothers and young son hated him for the Red taint. Picture picks up the double life as Gerhardt Eisler comes to Pittsburgh to ready the Red cell for strike violence and racial hatred.
Excitement and suspense are set up in the many near-escapes from exposure that Lovejoy goes through before he completes his job by revealing Commies and their activities before the UnAmerican Activities Committee. There’s a brief touch of romance, too, in the person of Dorothy Hart, a card-carrying schoolteacher who finally sees the light and is saved from Commie reprisal by Lovejoy.
