This movie is a real must see for Sanders fans. It's an adaptation of the "Prisoner of Zenda"...Sanders plays an unwilling part in a Great War "sting", to capture vital enemy secrets, due to his uncanny resemblance to a top German officer. The result is an action packed thriller with a nice quirky ending. Watch out for Dolores Del Rio as a splendid Marta Hari figure....just darn excellent!
