Olympia(1930)

Theodor Shall is cast as handsome Lieutenant Kovacs, the sweetheart of the lovely Princess Olympia. When the princess' snooty mother breaks up the romance, the embittered Kovacs threatens to tell the world that he has "ruined" the girl (not true!), making her unfit for marriage. To ensure his silence, the Lieutenant is promised a night alone with Olympia, just before the wedding. It is at this point that Kovacs proves he's a gentleman after all by marrying the Princess, which is what he intended to do all along.
