If you’re talking about that teaser from about a month ago which featured a 4 made out of spiderwebs, that was actually for something completely different
To be fair I think the first two Superman movies where the only ones to be truly good. Everything that came after that (except for Superman returns) was pretty bad.
I agree. Not as good as the original ones, but still pretty decent. And the cancelled sequel didn’t sound that bad either.
If anybody here is interested in the behind the scenes of movies (especially cancelled ones), I highly recommend you all give The Death of “Superman Lives”: What Happened? by the late John Schnepp a watch.
