Just the words "Harry Carey" are usually enough for a movie to rate at least an 8, but this film has much more: Real Mexicans playing Mexicans.And there is Kane Richmond in a less-than-admirable role.And the excellent Ted Adams as a far-less-than-admirable character.It's a story somewhat familiar, perhaps, but generally well presented, except for some unevenness in the story development.Whether that's the fault of director John P. McCarthy or the fault of writer John P. McCarthy is hard to tell.But the flaws are minor, finally, because of the cast and story and setting, a not too usual setting for the story of conflict and romance and greed and alcohol.Perhaps more even than Harry Carey, the actor to watch here is George F. Hayes, who essays an Irish accent that is one of the best. It is subtle, not the stage blarney-shillelagh-whisky Irishman that is sometimes funny just not very realistic. (IMDb's spell checker tried to tell me "whisky" should be "whiskey," but, sorry, not in Ireland.)Even later, when George F. Hayes became "Gabby" Hayes, he was still one of the very best B Western actors -- and that means movie actors -- we have been fortunate to watch.And watch is the thing to do. I recommend "Cavalier of the West," for its scope, its cast, and its entertainment value. Its available at YouTube, compliments of that great friend of mankind, Westerns on the Web.
