Ilya Muromets (1956)
Ilya Muromets, known in the US as The Sword and the Dragon and in the UK as The Epic Hero and the Beast (significantly altered versions), is a Russian fantasy film directed by the noted fantasy director Aleksandr Ptushko, made at Mosfilm and released in 1956. It is based on the byliny tales of the bogatyr Ilya Muromets. The film has some differences from the byliny but remains surprisingly true to the original epic poems.
