Nick Nadel is a comedy writer and blogger living in Brooklyn, NYWe're in a golden age of comic book movies right now, where even the most obscure comics (ahem, Cowboys & Aliens) can become blockbusters. But while fans have gotten movie versions of everything from Ghost Rider to Kick-Ass, there are still plenty of comic book movie properties that fall through the cracks. Recently, filmmakers like Joss Whedon and George Miller have spoken up about their failed would-be comic book franchises. Let's take a look at Whedon's Wonder Woman, Bradley Cooper's near performance as The Crow and other comic book movie "might-have-beens."
Fans of DC's Amazonian warrior princess had their hopes dashed when Joss Whedon's proposed Wonder Woman flick fell apart several years back. Recently, Whedon revealed some details about his take on the iconic hero. "[Wonder Woman] was a little bit like Angelina Jolie ... she sort of traveled the world," Whedon said. "She was very powerful and very naive about people, and the fact that she was a goddess was how I eventually found my 'in' to her humanity and vulnerability. ... She would look at us and the way we kill each other and the way we let people starve and the way the world is run and she'd just be like, None of this makes sense to me." Whedon added that in his original screenplay, Wonder Woman's romance with Steve Trevor would also help to humanize her. An interesting take on a character that DC has so far failed to get a handle on for the big screen. Of course, Wonder Woman fans' loss is Avengers fans' gain. The Crow Reboot
Recently, concept artwork was released from director Juan Carlos Fresnadillo's failed reboot of James O'Barr's enduring goth icon. The planned update was to have starred The Hangover's Bradley Cooper in the role made famous by the late Brandon Lee way back in 1994. But, as with many projects related to the seemingly cursed Crow franchise, Fresnadillo's reboot fell apart once Cooper dropped out due to scheduling conflicts. As evidenced by the concept art, the new Crow would've had something of a Western punk rocker thing going. Diego Latorre's grim drawings (which originally appeared on Shock Till You Drop) are also proof that the jovial Cooper was completely wrong for the Eric Draven role. With The Crow, casting is everything. (Didn't the producers learn anything from Edward Furlong's over-the-top performance in the dreadful fourth film The Crow: Wicked Prayer?) 
Justice League Remember when Warner Bros. was working on a Justice League movie? Well, director George Miller (Happy Feet) talked to Superhero Hype recently about what happened to Warner/DC's answer to The Avengers. Turns out the 2007 Writer's Guild strike was only part of the problem. "There [were] a whole bunch of complex events," Miller said. "It was the middle of a writers' strike. There was Australian rebate legislation that was required to get the film going. ... It was no one particular's fault that it didn't happen." At one point, the film was ready to go with Adam Brody as the Flash, DJ Cotrona as Superman, Megan Gale as Wonder Woman, Common as Green Lantern, and the then-unknown costar of The Social Network Armie Hammer as Batman. After the project fell apart, Miller went on to work with Common in the upcoming Happy Feet 2. As for Justice League, it's sadly still languishing in development hell while Avengers rockets toward the big screen.
Throughout the '90s, Avatar guru Cameron tried for years to get a Spider-Man film off the ground, only to face a protracted legal battle between defunct studio Carolco and various other parties that was more epic than a Green Goblin-Peter Parker face-off. Last year, Cameron's illustrated script treatment surfaced, providing a peek at what might have been. Featuring Electro and Sandman as the primary villains, copious profanity, and a racy Peter-Mary Jane sex scene, Cameron's take on Marvel's wacky wallcrawler was far more mature than Sam Raimi's 2002 film. One element that remained from Cameron's treatment? Those divisive organic webshooters. So feel free to blame James Cameron for that one. 
Before bouncing back with Superman Returns and Batman Begins, DC's top superheroes floundered throughout the late '90s and early '00s. Everything from a third Joel Schumacher film (tentatively titled Batman Triumphant) featuring Scarecrow and Harley Quinn to an adaptation of the Batman Year One comic helmed by Darren Aronofsky was considered for the Caped Crusader, while Superman projects were tackled by the likes of Tim Burton and McG. (Who could forget Nic Cage's bizarre Superman costume that leaked a while back?) At some point, Warner Bros. just gave up and decided to combine the two franchises for the ultimate superhero smackdown. Director Wolfgang Petersen was attached to the project but eventually left to make Troy. The story found Superman battling a Batman who was driven to the edge by the deaths of Robin, Alfred, and Commissioner Gordon. (Of course, they eventually team up to take down Lex Luthor and Joker.) The strange project, which also involved Joker killing Batman's fiancée and Clark Kent dating Lana Lang, ended up being referenced in the least likely place -- as a fake movie poster in I Am Legend's post-apocalyptic Times Square. (Legend screenwriter Akiva Goldsman also worked on Batman Vs. Superman.)
