The story may be about a thoroughbred horse named Black Gold who entered the classic Kentucky Derby, but I found the real story was about an innocent victim named Charley Eagle (Anthony Quinn) whose lack of knowledge of the white man's scrupulous ways to take advantage of the less fortunate was so prevalent in the 1940's and the decades earlier.
In the current decade of the 2020's we still have hundreds of thousands of shady characters who hide behind software and telephone scams to swindle the elderly and new immigrant populations across the world. Back in this 1947 film Charley enters his race horse in a claiming race and when his horse wins easily Charley's initial joy is lost when he learns that his horse has been claimed for a paltry sum by a scrupulous individual who is happy to take the winning horse into his own expanding winning horse stable.
Long before Jed Clampett and the (1962-1971) TV series, The Beverly Hillbillies struck gold, black gold, texas tea, as they called it, the humble but proud farmer Charley Eagle struck oil on the land he owned and unlike the fate that took away his prized racehourse through a claiming race, Charley had a reputable engineer and friend who ensured Charley would reap the financial benefits of his large oil strike on his land.
Yes, there is a dramatic horse race to be run, and yes poor Charley experiences both the highs and lows of winning and losing, but that is how life takes most of us by surprise.
I give Black Gold a passable 5 out of 10 IMDb rating.
