Three scenes utterly traumatized me as a youngster:
1. the reveal of the “star child” in 2001: A Space Odyssey (nightmarish!);
2. the rabbit attack in Monty Python and the Holy Grail (that was a lot of blood); and
3. the finale of Disney’s The Black Hole, wherein an ostensibly family-friendly flick suddenly goes medieval and takes a trek through literal Hell. After 80 minutes of cinematic sci-fi — ending with the entire cast being sucked into the eponymous hole — Dr. Hans Reinhardt (Maximilian Schell, Deep Impact), imprisoned within the armor of his killer robot, stands guard over a blasted hellscape as tortured souls trudge down pathways carved into a flaming mountain range.
