The Mad Genius

John Barrymore stars as Vladimar Tsarakov, a crippled dance enthusiast who runs a traveling marionette show with his partner Karimsky (Charles Butterworth). After a show in Central Europe, they notice a young boy (Frankie Darro) being chased by his abusive father, with the boy displaying strength and grace of movement. Tsarakov smuggles the child away, and raises him to adulthood. Named Fedor (Donald Cook), the young man has become perhaps the greatest name in ballet, but his life is completely dominated by Tsarakov, who does everything in his power to make sure the young man stays focused, even if it means chasing away his new beloved Nana (Marian Marsh). Also featuring Boris Karloff.

Barrymore gets to go wild-eyed and over-the-top, while Cook makes for a leaden leading man. Butterworth's comic relief is amusing but seems out of place. Karloff has a small, unbilled role as the young Fedor's abusive father. I liked how Tsarakov maintains control over manic director Alberni by plying him with cocaine.
