Must have been late 70s.
There’s some rock star on stage. Above the stage, behind him, in the proscenium arch, there’s a door that opens. Some big mechanized insect thing looks out on stage while the guy is performing. Then a moment or two later, you see some solid prop representing a bolt of lightning coming out of the door, and it shoots down onto the stage and kills the rock star guy.
TIA!
“Phantom of the Paradise” (1974)?
I think this is the scene. Found it on YouTube.
Solved!
TY Livinghead. This craziness is one of my earliest memories. I saw this scene on TV around 1977 or 78.
Thank you vinvan.
