They don't make movies like this any more. Maybe it's just as well, though it's amusing enough, in a 'time capsule' fashion. Adolphe Menjou, George Raft, and Sidney Toler are as unlikely a trio of Mexicans as you're ever likely to see, but then these were the days when you could cast Humphrey Bogart as an Irish stablehand (Dark Victory) and people would accept it. Not a bad timekiller, though you wouldn't want to watch it more than once.
