Ambassador Bill on AllMovie

Bill Harper (Will Rogers), a cattle baron turned diplomat, is assigned to the middle European country of Sylvania, which is in a nearly constant state of uproar ever since King Lothar (Ray Milland), who is convinced Queen Vania (Marguerite Churchill) was having an affair, left the country. Their young son Paul (Tad Alexander) is supposedly the leader, but it's really ruled by scheming Prince de Polikoff (Gustav Von Seyffertitz), who instantly dislikes the easygoing Bill, who makes friends with Paul and Vania. Lothar, who sneaked back into the country disguised as Bill's pilot, tries to reconcile with Vania, but to no avail. Thanks to de Polikoff's plans, Bill is arrested -- just as Lothar starts a revolution.
