It is a delight to be able to watch such a great film as this, and not at all easy if, like me, you live in the UK, where pre-WW2 Gable films (with the exception of "Gone With The Wind") are inexplicably very hard to find on sale in the necessary Region 2 or even All-Regions format). Anyway, this film, based on the great American oil-exploration boom days of the late 19th century, has just about it all : an entertaining and twisting story-line, with the rigours and excitement of trying to strike oil against a background of frontier-spirit adventure, in which it didn't do not to be ready to fight your corner, as well as hold your liquor, as well as quite a sea-change in the plot as the action switches from the Wild West to New York, where Big John McMasters (Clark Gable) has resolved to build himself an empire based not just on the production. but also on the refining and distribution of oil and its products, especially, of course, petrol. There are many fine parts in the film apart from those played by Gable, Tracy, Claudete Colbert and Hedy Lamarr, but these four themselves are a galaxy of stars, and in this film they are all allowed to shine.
I'd have given it 5 stars, but then that would mean having to give SIX to some of Clark Gable's other films from this period and earlier.!
