With both the Batman and Superman franchises laying dormant in the early 2000s, Warner Bros. attempted to revive them both with one massive crossover pitting the two iconic superheroes against each other. Conceived by Andrew Kevin Walker and written by Akiva Goldsman, who infamously wrote the neon nightmare Batman & Robin, Batman vs. Superman was to be directed by Wolfgang Peterson. Meanwhile, WB was eyeing Christian Bale as the Caped Crusader and Josh Hartnett as the Man of Steel.

The movie was set to take place late in Batman’s career, with Robin, Alfred, and Gordon all being dead and a retired Bruce Wayne settling down for his wedding, at which a newly-divorced Clark Kent was to be his best man. His bride, of course, is killed by the Joker on their honeymoon, prompting Bruce to once again become the Batman. Somehow the plot would have then involved Lex Luthor pulling the right strings to make Bats believe Superman killed his wife, prompting the two comic book heavyweights to throw down in a massive fight that would have undoubtedly been fascinating to watch unfold.

The movie eventually got shelved to make way for Christopher Nolan’s Dark Knight Trilogy, which is just about the best thing to happen to the superhero movie genre in decades. Fortunately, fans looking for these iconic heavyweights to finally air their grievances on the big screen won't have to wait much longer
