My two all-time favorite "SCI-FI" (and I use the term very loosely) movies are, Attack of the 50 Foot Woman [1958] and Curse of the Faceless Man [1958] - admittedly, two of the worst films ever made. These films were staples on Chiller Theater, a Sat. night B-horror movie showcase that aired in the New York Tri-state area when I was a kid in the 60s. The lesser known, Curse of the Faceless Man, was basically a re-telling of the Mummy set in Italy with a volcanic ash-encrusted "preserved" slave who comes back to life after being dug up in an excavation, searches for (and finds!) the reincarnation of his one true love (of course, killing almost all who get in his way). I have never met anyone who remembers this flick. This movie scared the crap out of me as kid. The film's score was very effective!
