Well, the last post got me thinking about the stories which have not been adapted to animation yet. Well then!! Here's my list of stories that I think would be swell animated movies.
GREEN LANTERN/GREEN ARROW. The groundbreaking storyline written by Denny O'Neil with art by the legendary Neal Adams. which had the Green Lantern and Green Arrow tacking very topical story lines back in the early 1970's which included political corruption, prejudice and drug addiction. Which readers find out the Green Arrow's ward Speedy has become addicted to heroin. Which the Green Arrow in many ways has his comeuppance for his own forceful preaching and berating the Green Lantern with being out of step with the times while he himself has completely neglected his own ward because he was too caught up in his own affairs. I would love to see the animation done in Neal Adams style.
JUSTICE LEAGUE: THE NAIL. One of my favorite of the Elseworld stories. Great artwork by one of my favorite Batman artists Alan Davis who draws in the same school as Neal Adams and Jim Aparo as far as his interpretation of Batman is concerned. This one envisions a world if Superman had come to Earth but had never become Superman because Ma and Pa Kent decided because they had a flat tire they would stay in for the night instead. All because of a nail. Some really great scene with a Superman-less Justice League. And a great confrontation between Batman and the Joker when the Joker is given the power to torture and kill Robin and Bat-Girl right in front of a helpless Batman. And Batman finally snaps.
Captain Marvel Battles the Monster Society of Evil. I'm not talking about an adaptation of the miniseries by Jeff Smith (which I did enjoy for his style of art) I'm talkin' about an adaption of the original series by CC Beck!! Although, the good Captain had one of the best movie serials of the 1940's, very rarely have animators gotten him right or done his character any justice. He's usually getting his ass handed to him by Superman. And let's not get into that awful Filmation cartoon from the early eighties. The only exception is his recent appearance in Batman: Brave and the Bold. I would love to see an animation directly in Beck's style of the Big Red Cheese. I wouldn't completely oppose them adapting Jeff Smith's take on the original insanely long story arc of MSOF because of time constraint, I would much rather seem them tackle the original story.
Captain Marvel Battles the Plot Against the Universe. Another great CC Beck Captain Marvel story. This one the good Captain fights against his arch foe Dr. Sivana chasing him back in time and all the way to the Rock of Eternity where Sivana steals the wizard Shazam's bracelets which allows him to exist in his ethereal form and makes him immortal. Now Captain Marvel must race against time to not only save Shazam but also defeat all of Sivana's robot clones which he constructed out of a new alloy called Sivanium...
...by the way, the braclet Shazam wears is out of Shazamium... but it doesn't end there. Captain Marvel created a new alloy in the story called... wait for it...
...Marvelium.
I'll be honest, I liked the fact that CC Beck took an unapologetic cartoon approach to both his stories and his character design. It's what made the Captain Marvel tales fun. And if they were to adapt a story like this I hope they take the same approach.

There's not necessarily one
Teen Titans story I would love to see adapted. I would just love to see an animation of the Teen Titans with the original crew of Robin, Wonder Girl, Kid Flash, Aqualad and Speedy in Nick Cardy's style of art. As much as I enjoyed the anime inspired version on Cartoon Network (yes I admit it. I enjoyed the series) would love to see them at least tackle a one-off movie with the original version of the team. Perhaps sans Groovy sixties lingo, natch.
Green Arrow: Longbow Hunters. Still a favorite miniseries of mine after all these years. I think I was intrigued by Mike Grell's approach to comic making by inserting these panels that looked like they were charcoal studies. Which could have been distracting (or seemed lazy) but I liked it because it seemed somewhat different from the usual comics.
The story was written at a time where they were trying to make masked Superheroes a bit grittier. I think a lot of that was to do with stories like
The Dark Knight Returns and
The Killing Joke which were darker than your average comic book. You had all these Punisher-type characters "chewing bubblegum and kicking ass" all around comic books. So I suppose it was only a matter of time before GA hung up all his trick arrows and started using real arrows and actually pinning his enemies to the wall. And not smack them across the face with a boxing glove arrow.
I even liked the costume design. Which still maintained the Neal Adams looking GA but lost the Robin Hood/Peter Pan looking hat and gave him a hood. They even moved him to an actual city with Seattle and not some made up DC Comics type city (i.e. Gotham, Star City, Keystone City... um... Gorilla City). And he was dealing with drug dealers and not the usual costumed villain.
I'm not sure how a project like this would adapt to animation. It's quite a bit darker than any of the ones Warner animated so far. However, New Frontier did start out with a suicide.
And Green Arrow is another DC character that has never really gotten a real fair shake as far as animation is concerned till recent years with
Justice League: Unlimited and Batman: The Brave and the Bold. I mean, they cut all his lines out of the
New Frontier adaption. Which is a shame because I think Darwyn Cook made his character really interesting.
So, I think GA is a bit overdue to star in his own feature.

Last on the list is
The Untold Legend of the Batman. This is still my favorite of the Batman origin/history stories. This has everything. Not only the Joe Chill origin but also the Lew Moxon storyline where we discover that Chill was just a hired thug for Moxon who had wanted Bruce Wayne's father dead since he fought off Moxon and his henchmen at a costume party...
where he was dressed in a Batman style costume.
This story also includes the Red Hood origin of the Joker. But not the down-on-his-luck stand-up comic one from the Killing Joke. But the one that paints him as an unknown masked criminal before his face got permanently scarred after he jumped into a vat of toxic chemicals to escape Batman and Robin. It would be great to see it in both Jim Aparo and John Byrne's style.
