In case there was any doubt remaining, The Dark Knight co-writer Jonathan Nolan confirmed for ComingSoon.net that neither he nor his brother Christopher have any involvement in any of the ten upcoming DC Entertainment films slated for release starting in 2016.
"I love those guys and my brother was involved in Man of Steel with Zack [Snyder] and David [Goyer]," said Nolan in an interview in support of the brothers' upcoming film, Interstellar. "I kind of feel like that chapter for us is closed."
That said, according to the interviewer, he didn't rule out the possibility of an eventual return to the DC Universe.
"To be continued somewhere farther down the line?" Nolan suggested. "Maybe."
