- Animorphs. We even have the technology now. It could be so awesome.
- Shadow Hearts (PS2 game). This one could work if it was more "based on" the game than a direct adaptation. Otherwise it might hit that "too anime-y to take seriously" point live action anime can sometimes become. Really though it could go either way, comedy or totally serious. I just want that Roger Bacon plot twist in a movie (or tv series) though. That was brain breaking.
- USER is a 3 book comic published by Vertigo that probably nobody knows about but I think it'd make an interesting independent film. It's about a woman who rps online as a dude and falls in love with her rp partner, who ends up being a small boy. Her rl life is a shitfest and she runs away to meet her lover and watatwist!. It's probably something that wouldn't be so surprising now, but when the comic came out (2001), it was still kind of unexpected.
- Sword of Truth book series abridged into a movie would be neat. Maybe anger a lot of fans but I think this one, again, would be better as an interpretation rather than straight adaptation.
- Constantine / Hellblazer. It already exists but I'd love another one anyway.
- Arkham Knight. Specifically, the Professor Pyg storyline. I really really really want a psychological horror movie that just happens to have Batman in it (maybe). I want the movie to focus on Professor Pyg and his victims. I want it to be a horror movie first and Batman movie last.
EDIT:
- DRAMA CON. An English manga that would be cute as a movie or TV series. With how popular cosplay and nerd culture has become, I think the story would resonate with a lot of people.
