The Dresden Files, The Matrix, Dark City, American Gods/Anansi Boys, The Sandman comics, Doctor Strange, Hellboy, Lord of Illusions, The Men Who Stare at Goats, The Avengers, The Fisher King, The Crow, Akira, Crouching Tiger Hidden Dragon, Deus Ex, Neuromancer, Bioshock, Snow Crash, The Man In the High Castle, Constantine, Black Mirror, Jumper, Looper, Donnie Darko, Tim Powers books…hopefully you get the idea.
In all of the above stories, we have characters who not only seek, or have, supernatural powers, but who believe deeply. Their belief is what drives their engagement with the supernatural (or super-technological). Mages see the world as something that can be changed, and that should be changed, and Mages have the power to change it, for better or worse.
