Query: An Excellent Movie!!!

This is, oddly, one of my favorite movies. Marilyn, Jean Peters, and Joseph Cotton all act at their best, and the beauty of the falls adds beautiful, graceful scenery and suspensefulness to the movie as well. I first found this movie when watching the Marilyn Marathon on AMC when I was 10. I liked it so much, I went and bought it the next day. This movie hasn't one dull moment, and I am shocked that such a good movie could be out of stock. This movie kept on building and building suspense all the way up until the shocking, unpredictable ending. If you want a real classic suspense film, NIAGARA is the film for you.
