Several movies have been filmed in Niagara Falls, but few are more well-known than Marilyn Monroe's "Niagara" which released in 1953.
The movie is a mystery thriller about a murder plan gone awry. Rose Loomis, played by Marilyn Monroe, and her husband George, played by Joseph Cotten, are vacationing in Niagara Falls, NY when they befriend Polly and Ray Cutler, played by Jean Peters and Casey Adams, who are honeymooning. Polly suspects something is wrong between Rose and George. Her suspicions are later confirmed when she sees Rose with another man. With the influence of sex and destructiveness, things between George and Rose only get worse from there.
Although the movie takes place in Niagara Falls, NY, the movie was filmed in Niagara Falls, Ontario. Marilyn Monroe stayed at the Crowne Plaza throughout filming, which which was called the General Brock Hotel at the time. The cabins featured in the movie were built specifically for filming and then removed afterward.
