Issue #149 of the comic magazine, Wizard has a short article by Todd Casey, Hell on Film about Constantine (via keanuweb):

"Constantine" director casts an evil light on the noir thriller's L.A. set and sinister storyline.

Think downtown Los Angeles looks like a nightmare at rush hour? You should see it in Hell.

"Constantine," starring Keanu Reeves as the trenchant, embittered occultist John Constantine from DC Comics' Hellblazer series, follows the story of John as he teams up with policewoman Angela Dodson to help investigate the mysterious death of her sister Isabel, which leads him into a hellish version of his hometown.

"John goes into Hell to find Angela's sister to see if she has committed suicide," describes "Constantine" director Francis Lawrence of the elaborate set hewn from wrecked cars and barrels of brown muck. "What we've done is actually made Hell have geography so that you have the idea that wherever you are, there is a Hell version of it and a Heaven version of it. John goes to Hell and it's literally the 101 Freeway heading toward downtown L.A."

Deep in "Hell L.A." (and even on the sunny streets of the city itself), Constantine comes up against legions of half-breed demons who inject evil into mankind's world. When he's not kicking their asses with an array of holy relics, Constantine kicks back in his apartment (located over a bowling alley), safely insulated from Hell's spawn with a few dozen five gallon drums of holy water.

And in the next issue (due out Feb 25), look for more Constantine content.
From the Wizard website:

He can fly. He can fight. And he's certainly heroic. Keanu Reeves has already played the ultimate superhero as Neo in "The Matrix" trilogy. Now get ready for him as the ultimate anti-hero.

As part of its massive 50-page movie event in Wizard #150, Wizard sits down with Reeves, who trades in Neo's flowing coat and sunglasses for a plain old shirt and tie as the sarcastic anti-hero John Constantine, who attempts to prevent demons from turning L.A. into a hell on earth in the September-released film "Constantine," based on the DC/Vertigo comic Hellblazer.

The normally publicity-shy Reeves shares with Wizard his love for Alan Moore's V for Vendetta comic, his favorite comic movies and the complete scoop on why the character of Constantine appealed to him. ''I really love playing him,'' admitted Reeves between pulls on a cigarette while taking a break in his trailer. ''I liked his anger. As an actor, it's really fun to play someone who is wounded but fighting. I like his never-give-up attitude and his gallows humor.''

For the complete interview with Reeves - and exclusive photos from the ''Constantine'' set - pick up Wizard #150 on sale in comic shops Feb. 25.

I'm going to have to call my comic guy and make sure he holds one of these for me.
