Despite Stephen Longstreet and Harriet Frank's too verbose screenplay (was it really necessary to give Thomas Mitchell THREE condemnatory speeches of Errol Flynn when one would do?) and noted action director Raoul Walsh's obvious discomfort with examining the vicissitudes of the passionless Ann Sheridan/Bruce Bennet marriage to say nothing of trying to enliven business intrigue centered around cornering the silver market, I kind of enjoyed this rare foray of Flynn into anti hero-dom. Don't know whether it's because it mirrored what was going on in his private life or if he's just an under rated actor, but the guy does dark complexity of character rather well, in my opinion. Give it a B minus.
PS...The scene with U. S. Grant has to be the most superficial Hollywood portrayal of an American president until Pat McCormick essayed Grover Cleveland in Altman's "Buffalo Bill And The Indians", (another flawed but fun western).
