The Magic Flame (1927)

A beautiful trapeze artist is loved by two men, identical in appearance but opposites when it comes to their station in life and their personalities. One of the men is Tito the Clown, a gentle and kind man whose love for Bianca is pure; the other is a heartless and wicked Count who is bent on possessing Bianca, even against her wishes. Tito goes to rescue Bianca and ends up killing the Count, so he must take the place of his evil doppelganger to avoid being charged with his murder.
