The Unearthly
A mad doctor uses patients at his isolated psychiatric institute as subjects in his attempts to create longevity by surgically installing an artificial gland in their skulls.
Critics Sentiment
Police discover Conway's menagerie of failed experimental subjects in basement
Natalie undergoes surgery and becomes a senile old woman
The film's weakest point during Natalie's poorly executed transformation gives way to its strongest moment with the memorable basement reveal of Conway's failed experiments.
The Unearthly maintains consistently low audience sentiment throughout most of its runtime, with reviewers citing poor pacing, dreary cinematography, and budgetary limitations. While Tor Johnson's presence and the attractive cast provided some entertainment value, the film only truly succeeds in its final act with the memorable basement horror reveal. Despite being widely considered one of the worst films ever made, critics acknowledged it as more bearable than similar B-movie disasters.
