although humphrey bogart get star billing in king of the underworld and i be willing to bet he do not thank jack warner for it . in fact this film be one hollow crown . king of the underworld be supposedly a remake of the paul muni film and dr. socrates and but give humphrey bogart be in the cast and the character be write more like duke mantee in the petrified forest . he even have an english writer along in the person of james stephenson . kay francis and john eldredge be a pair of married doctor and eldredge pull off a tricky bit of surgery on one of bogart henchman . bogey a man who appreciate good work do on his behalf and give eldredge $ 500 . 00 and there more where that come from if he play his card right . eldredge who have a gambling problem see a good way to get some undeclared income . but when he kill in a raid on the gang hideout and francis be also think to be involve by the law and the american medical association no matter how much she protest her innocence . it no good and she and her aunt jessie busley move to a small town to get away from the notoriety . of course the notoriety and bogart and an itinerant leslie howard like writer in stephenson all meet up with her again . but kay be plucky and resourceful to say the least . bogart character be ridiculous and no wonder the poor guy be scream for good part . he a gangster who both shoot down people without mercy and give his henchmen hotfoot just for laugh . he concern about his image and therefore kidnaps writer stephenson to ghost write his autobiography and of course confesses enough to burn him in all 48 state . and then let kay francis completely outsmart him and hard to believe he be king of anything . definitely one of the less work for either of the star .
