Vastly entertaining mystery movie/1930s newspaper comedy about master criminal (Reginald Owen) who finances a World War I play with on-stage explosions to cover up below-ground explosions needed to break in to next door bank vault where the priceless Sunburst diamond he covets is locked up in the vaults. Thoroughly preposterous plot but who cares! Delightful hard-boiled, wise-cracky romantic comedy between ace-reporter/criminologist Joel McCrea and sassy but adorable actress (Jean Arthur). Thomas Mitchell rants and raves as the newspaper editor, and Herman Bing has a delightful cameo as the German owner of the club where newspapermen hang out. Suspend all disbelief and enjoy yourself.
