Any story from any kind of medium adapted to film or TV (series, mini, or otherwise).
If I could direct a live-action version of Throne of Atlantis or the Court of Owls, I would basically change nothing. Particularly issues 10 and 11 of CoO is almost perfectly paced and laid out for a film.
I would however put Green Lantern and Shazam in place of the reserve members Cyclops booms in to help in ToA. I also don't know if Cyclops would be in the movie.
