This fan-made trailer from Stryder HD makes a compelling argument that it would have been pretty cool to see the two ‘80s cinematic superheroes face-off on-screen. Bonus points for realizing Lex’s plan to use Zod’s body to create his own Kryptonian in BvS lines up eerily well with Lex’s plan to make his own whatever-the-hell-Nuclear-Man-was from one of Superman’s hairs in The Quest for Peace.
Rob Bricken was the Editor of io9 from 2016-18, the creator of the poorly named but fan-favorite news site Topless Robot, and now writes nerd stuff for many places, because it's all he's good at.
My problem with these fan made trailer mash ups from old movies is a) they’re always too long, they should be the length of an actual movie trailer (2 minutes 20 max) and b) they cut them in the same style as movie trailers now with the music and bwarrrr sound effects to go with it. It'd have been much better if they'd done it as if it was a film from the 1970s/1980s.
