"Mogambo" (1953) is a good film with an excellent ending that makes you want to watch it again. Of course, the excellent cast and the place where the story was filmed help, and a lot.
This movie was directed by John Ford, and filmed in Africa. The plot is simple, but quite effective. Victor Marswell (Clark Gable) is a safari guide whose like is disrupted when a beautiful woman, Eloise Kelly (Ava Gardner), shows up at his camp, looking for a majarajah. Unfortunately for her, her "acquaintance" has left and she has to remain in the camp at least until the next boat arrives. Eloise starts to fall for Victor, and their attraction seems mutual, but not meant to be.
However, things are further stirred up when a couple, Professor Donald Nordley (Donald Sinden) and his wife Linda (Grace Kelly) arrive to Victor's complex for a safari. The problem is that now Eloise likes Victor, Victor is attracted to Linda, and Linda has feelings for Victor but is married to Donald, who is not aware of what is happening around him and is only interested in looking for gorillas.
Of course, that situation is a good recipe for entertainment. Throw in a great scenery and some wild animals, and you have a very entertaining movie. All in all, I give this movie 3.5 stars, and I think it is worthwhile to recommend it :)
