The River of No Return is certainly not a great movie. It is a good movie, an entertaining movie, a fairly well-written movie with a good cast and Marilyn Monroe looks great in the movie. This movie was also ahead of it's time at least when it comes to women's fashion. This movie takes place in the late 19th Century or early 20th Century and yet Marilyn is wearing tight Lee denim jeans in boots for about half of the movie. In an era where that was almost never seen from women. Back then women wore long dresses for the most part and nothing that showed a lot of their physical body.
Marilyn looked great in this movie, her usual hot sexy baby-face adorable sweet self. And this movie was very real to me in the sense that it wasn't about angels and devils. Robert Mitchum plays a single father in the movie who helps out a couple on the water having trouble with their boat. The man in this couple is a criminal or crook on the run. His wife is Marilyn a sweetheart, but not someone without faults. But Mitchum is simply trying to help these people out and the guy screws them and takes his lone horse away from Mitchum and his son and his girlfriend stays behind with the man and his son. And now they are together trying to survive on the River of No Return with outlaws shooting at them.
