Legend (1985)
Played by Tim Curry
The Devil wears A leather waistcoat, a ton of prosthetics and a pair of ridiculously oversized horns.
Most Satanic moment Shamelessly trying to kill the last two unicorns in the world. Presumably because his own horns arent big enough. Add on the shiny red skin, the trident and Tim Currys maniacal grin and they dont get much more Devil-ish than this.
