SWORD AND THE DRAGON 1956 (SINISTER CINEMA)

Magnificent adventure film from Russia about a man who is crippled but when he offers help to several strangers they give him a potion that makes him strong again and he sets off to fight the army that has pillaged his small village.
He fights the evil ruler and his army as well as a wind demon, evil spirits and a huge three headed flying dragon.
The Russians always knew how to make excellent fantasy films, and this is one of many. It was cut for US audiences and re-dubbed, but it is still an epic that I really recommend you see if you have a chance.
