Right, this is pure mystic craziness with a side order of batshit crazy. What we have here is a war between magicians. They aren't however the Harry Potter type of magicians on their broom sticks. Nor are they the Doctor Fate type with flashing bolts of energy. These mystic, mages, and crazy people find various ways to coax reality to follow them instead of the where it should. If that means being a transvestite who lets himself be ridden by Mayan gods then so be it. Or a dapper assassin cut from the cloth of a Moorcock hero, then let it be.
Movie could cover the first two arcs of the Invisible story. The first is introducing a foul mouth little thug into the Invisible cell and magic. The second is the weird tale of how the Invisibles have to mentally travel back in time and save De Sade of all people and bring him back to the future. It would be like a David Lynch film ala James Bond.
