According to a February 1, 1952 Los Angeles Times news item, James Mason was originally set to star in this film. A March 19, 1952 Hollywood Reporter news item announced that Anne Baxter would be co-starring with Joseph Cotten in Niagara [as "Polly Cutler"], and modern sources assert that Baxter withdrew from the project after Marilyn Monroe was cast in the film and Monroe's part was re-written and enlarged. Contemporary sources note that portions of the picture were shot on location on the Canadian side of Niagara Falls. According to a July 1952 Hollywood Reporter news item, The Starlighters were to be the vocal group heard on the record of "Kiss," but their participation in the completed picture has not been confirmed.
Niagara marked Monroe's first appearance in a Technicolor film. In February 1953, Variety and Los Angeles Mirror reported that various women's groups were protesting Monroe's "frank characterization" in the film, although Twentieth Century-Fox reported that she was receiving "an average of 12,400 fan letters a month" and that the small amount of negative publicity surrounding the film had not hurt her career. In April 1953, the Niagara Falls representative to the Ontario legislature protested that the film "did the honeymoon capital nothing but harm," according a Los Angeles Herald Express article. The representative stated, "instead of a movie to show our school children, they give us murder and suicide and seamy lives." According to a modern source, the film cost approximately $1,250,000 to produce and grossed more than $6,000,000.
