Douglas Fairbanks Jr. played well in both roles as the twin brothers. Ruth Warrick was gorgeous as Countess Gravini. Akim Tamiroff was perfect as Baron Colonna and John Emery as his cousin,Tomasso. J. Carrol Naish was wonderful as always as the caretaker of Brother Lucien, the almost bad brother. The old time actor H.B. Warner was excellent as the doctor who separates the twins at birth, and takes care of them as adults. The action was good and comical at times. The ending sword play was fine and ended in a good conclusion. I highly recommend this movie.
