So, in the Superman movie — and yes, I am still talking about the movie — Lex Luthor has just deduced that Kryptonite will kill Superman, and he’s heading to Addis Ababa for an off-screen meteorite shopping trip. But the movie was out of date — according to the Superman comics of 1978, Kryptonite didn’t exist anymore.
The folks at DC Comics may have been excited about the upcoming Superman film, but there was a quiet war going on between the comics and the movie, battling to see which version of the story would take hold of the popular imagination. As it turned out, the movie won by a wide margin, and to explain why, all I need to do is show you what they tried to do with Kryptonite in the early ’70s.
