Uan Muhuggiag is a place in the central Sahara located in Libya, and the name of the mummy of a small boy found there in 1958 by Professor Fabrizio Mori. The mummy displays a highly sophisticated mummification technique, and at around 5,500 years old is older than any comparable Ancient Egyptian mummy.
Sorry, but for now we weren't able to find movies like The Mystery of the Black Mummy.
