For creepy, unsettling mummy movies there's nothing better than a classic Universal or Hammer Films feature. Hammer's The Mummy(1959) is my favorite with Christopher Lee. Coming in at a very close second: THE CURSE OF THE MUMMY'S TOMB(1964), produced and directed by Michael Carreras and released by Hammer Films.
This marvelous horror movie can be bought online at Amazon and is part of a four film DVD set called Icons Of Horror Collection-Hammer Films, released back in 2008. To buy this release click the link: ICONS OF HORROR COLLECTION - HAMMER FILMS
