Here is the 1945 film entitled, A Royal Scandal, starring Ms. Tallulah Bankhead and Mr. Charles Coburn.
Directed by Mr. Otto Preminger the film is set in 18th century Russia, where the naïve and idealistic lieutenant Chernov meets Empress Catherine the Great who becomes infatuated with him and appoints him Chief of the Imperial Guard.
My favorite line in the movie:
“And, may I add that Your Majesty is looking quite beautiful this morning!”
Hope you enjoy the film!
