Director Christopher Nolan ("Memento") has been signed to helm the next "Batman" movie, reports Variety. "All I can say is that I grew up with Batman, I’ve been fascinated by him and I’m excited to contribute to the lore surrounding the character," Nolan said. "He is the most credible and realistic of the superheroes, and has the most complex human psychology. His superhero qualities come from within. He’s not a magical character. I had a fantastic experience with the studio on ‘Insomnia,’ and I’m keen to repeat that experience." It’s not yet known whether he’ll write the script and whether the story will impact the other ‘Bat’ films in the works.
