For every Batman Begins and Spider-Man that actually makes it through the development process, there are a ton of comic-book movies littering the studio shelves in development hell.

Sure, we know about the ones that look like they would’ve been terrible (See: Superman Lives, that half-baked Justice League in 2007, Raimi’s Spider-Man 4), but what about the aborted superhero movies that could’ve been hits?

Or if not box office hits, at least pretty good movies?

From J.J. Abrams to Joss Whedon, a lot of big names have had their best intentions crash and burn on the way to the big screen. You can blame everything from casting battles to studio interference, but the only thing that really matters is they died a quiet, sad death.

So what were some of the coolest movies we never got to see?
