10 Famous Unmade Comic Book Movies We WISH We Could Have Seen

10. Wolfgang Petersen's Batman V Superman

Superhero crossover movies have become such a regular occurrence these days that we're used to them by this point, and it would have been interesting to see a mega-budget showdown like Batman v Superman spring up out of nowhere back in the mid-2000s without establishing either character in their own solo outing first.

While the script by Seven writer Andrew Kevin Walker that's circulated online isn't the greatest, Akiva Goldsman recently claimed that his re-write would have been 'the darkest thing you'd ever seen', and he might have been right. The movie was said to open with Alfred's funeral, before the Joker ends up killing Bruce Wayne's wife and the two title heroes eventually come to blows over their disagreements surrounding the Dark Knight's quest for vengeance.

Wolfgang Petersen, the thinking man's Roland Emmerich, was set to direct with Colin Farrell as Batman and Jude Law as Superman, with a release date even set for the summer of 2004. However, the studio eventually soured on the idea and made Catwoman instead, which turned out to be a great idea.

Of course, we eventually ended up with a relentlessly dark take on Batman v Superman over a decade later, while Petersen's abandoned project had to make do with a visual cameo in I Am Legend. Back when cinematic universes weren't even a thing, it would have been a huge deal to see DC's two crown jewels go head-to-head on the big screen for the first time ever.
