The Abominable Dr. Phibes/YMMV

The original movie contains YMMV examples of:

 * Older Than They Think: The last challenge, based on the Plague of the Death of the First-Born Son, requires the surgeon who failed to save Phibes' wife to cut out a key planted from behind his own son's heart that will allow him to deactivate a machine that will spray acid into his son's face if he takes too long getting the aforementioned key. This might as well be a prototype for the Saw films.
 * Also, this is a film about a man with burned skin, supposedly dead, who takes revenge on those responsible, sometimes through their children. Hmmm.
 * And although the idea of the Poetic Serial Killer goes back way before this movie, it's fair to say that Se7en may have gotten some inspiration from Phibes' extreme creativity and use of religious motifs.
 * Squick: "And then he'll have a face... 'LIKE MINE!'"
 * Uncanny Valley: The clockwork band.

The sequel, Dr. Phibes Rises Again, contains YMMV examples of:

 * Contested Sequel: Let's leave it at that.
 * Magnificent Bastard: Phibes.
