Sword And The Dragon, The (1956)

aka: Ilya Muromets

Ilya (Boris Andreyev) is a cripple without the use of his legs. When he aids some weary travelers, they surprise him by giving him a potion that restores his legs. He immediately becomes powerful and sets off to prove himself to his King. Doing so, he must now fight the evil Tugars, a wind demon that looks like a cross between a goblin and The Noid, a zeppelin-like ambassador. Later, Ilya gets framed for a crime he didn't commit, then is freed and finally dispatches the Tugars and their dragon. Also stars Shukur Burkhanov and Andrei Abrikosov. English language version of Ilya Muromets, also available here at Rare Movie Collector.
