The Woman on Pier 13 is what this movie was really called, the I Married a Communist (1949) title did not set well with all of the black list investigations in the early 1950's. This film was not released until 1950. It kept one interested and I feel it was mainly because of character actor Thomas Gomez (1905-1971). He always was an interesting character in his other films like the Sherlock Homes series with Basil Rathbone & Nigel Bruce. You noticed I don't mention the other actors in this film, it's because Thomas Gomez as Vinning was the STAR.
