The Green Hornet did not originate as a comic book, but it has been published as one. I think it would be perfectly viable as a TV series, as it was during the 1960's.
Fables (it even comes with its own spin-off, Jack of Fables) Gotham Central (but only if they're allowed to use Batman, which has always been the sticking point) Starman Daredevil Astro City
I want to add Sleeper. The boys, and preacher would be wild but no studio in their right mind would want to tackle that. I think the key for comics to transition into TV land, is comics which don't require a lot of CGI and spandex.
Wow! Great minds think alike! I've been wanting to see a film or TV version of this character for years, so I agree.
Hellblazer Surprised it hasn't happened before. Seems to me like it could be the perfect example of an episodic supernatural TV show. But maybe British channels haven't been looking for a supernatural horror/drama series.
Brian Vaughn and Tony Harris' excellent series Ex Machina (http://en.wikipedia.org/wiki/Ex_Machina_(comics) ) about a former super-hero who is elected Mayor of New York City. Would probably work best on HBO or Showtime.
She-Hulk. I mean hey you got a hot looking green chick, she's a lawyer, her clothes rip easily and she's got the silliest rogues gallery ever! Not to mention Marvel films has the rights to the Hulk so they could have Brucey or just the Hulk without Puny Banner show up, they could even have RDJr cameo/guest star as Tony Stark or Iron Man's voice/HUD during an episode or something. I'd adapt the original Byrne series and a little of the more current one. I'd keep the fourth wall breaks. That's what makes it kinda fun too. It'd be like WWE meets Ally McBeal meets the Incredibles meets reality TV
Not only is Green Hornet coming out later this year with Seth Rogen but Kevin Smith has a comic coming out that is derived from his abandoned script. Anyways here are my top five: Ex Machina Y The Last Man The Authority (probably would have to be a HBO series) Ultimate Spider-Man (despite my own personal opinion that this is what Mark Webb and James Vanderbilt are turning into the new trilogy) Astro City
Ok, I will add another... Spawn. I think Spawn needs another round on TV...as live action, not cartoon.
