Bryan Hitch certainly has JLA chops, including a major oversized JLA graphic novel under his belt, Heaven's Ladder. But, as part of June's mini-relaunch, he will be both writing and drawing a new Justice League Of America series for DC Comics. We recently saw Hitch write and draw his own series from Image Comics, Real Heroes, with it's final issue on the way.
Hitch was responsible for the emergence of the "widescreen comics" style, which was used effectively on the series by Jim Lee and Ivan Reis. It's a good chance to claim it for his own.
Say, I wonder if he'll be able to draw any of the cast of Doctor Who into this one?
