In Ian Fleming’s novel of “From Russia With Love” the movie poster for the 1953 movie “Niagra” starring Marilyn Monroe and Joesph Cotten covered the billboard that served as one wall of the shack where the Bulgarian hitman Krilencu makes his hide-out. Krilencu’s escape trap door is lined up with Monroe’s mouth. As this scene in the novel is set in Turkey, on the poster the movie title is spelled as NIYAGARA. (A detail that is duplicated in the artwork of the Daily Express comics strip adaption.)
As “Niagra” was produced by 20th century Fox rather than normal Bond distribution company United Artists, in the 1963 movie version of “From Russia With Love” the poster was replaced by one promoting a contemporary UA film “Call Me Bwana,” featuring Bob Hope and Anita Ekberg.
