Swamp Thing - No not like those Wes Craven films, but something that can create a DC Cinematic Universe. Make Swamp Thing the antagonist like in ManThing, the protagonist? Animal Man.
Nova - An idiot who gets powers and can't use them properly, why the hell not?
Ghost Rider 3 - Part one was bad, part two was okay [fuck the critics], part three can be stellar.
Magik - Might now be one of the X-Men's stellar characters, but she can do good on a solo film that derives nearly completely away from the comics but stays true to it. I can see Proteus as being a good villain for this film.
Black - Ted Dekker and Lionsgate, YES!
Skulduggery Pleasant - Be a nice movie, with Adrian Brody! BAM BITCH!
The Last Apprentice - Sure its being made the Seventh Son and Ben Barnes is a good actor, but they could choose a way better title instead of one that inferences that somebody needs a vagina vacation, maybe The Spook. They should keep it true to the book, but make it in the fashion of a thriller film with an original plot based off the plot of the first novel.
Tales from Sinister City - Sin City - but fantasy.
