Story of the Mormons given the big-budget historical melodrama treatment. A respectful but stiff film, with some fine performances, though of course historical accuracy was not high on Hollywood's priority list. It is accurate in pointing out that America has always been intolerant of anyone different (if you don't believe that, take a look around). Interesting to see Vincent Price and John Carradine onscreen together and muse upon their future careers!
Note: Many sources list the title as "Brigham Young - Frontiersman" but this was a promotional title, and is nowhere in the actual film. Also, IMDb lists Eddy Waller as "Man with California Gold News," but I am certain someone confused him with Paul E. Burns (either that or he was recast).
