Marilyn Monroe at Niagara Falls to make a downer of a movie

Marilyn Monroe poses on a railing overlooking Niagara Falls in this publicity photo from the 1953 film Niagara. We're not sure why she's smiling, because the film, directed by Henry Hathaway, was a gloomy and depressing noir about a bunch of unappealing people who cheat and scheme against each other. At the end, Monroe's husband (Joseph Cotten) strangles her, then plunges to his death over Niagara Falls. Both characters deserve it because they were lousy people who weren't much fun. Nice views of the falls, though! That same year Marilyn Monroe made the romantic comedies Gentlemen Prefer Blondes and How to Marry a Millionaire, so props to her for showing some range. But still, ugh.
