It looks like Jay Oliva, who directed three of Lionsgate's Marvel animated movies and co-directed Green Lantern: Emerald Knights (the "Mogo Doesn't Socialize" and "Laira" segments), will step in as one of the main directors of the DC line. The bulk of the workload will probably be split between Oliva and Sam Liu.
I was hoping for Joaquim Dos Santos to take over, but the "Laira" segment of GL:EK was the most impressive one on the entire DVD, so that's good news.
Still, it'll be unfortunate if the DCU movie line is left without any women in key creative positions. It's hard enough as it is to avoid an overly male-dominated viewpoint in superhero comics and their adaptations.
