Last week, Christopher Nolan's brother Jonathan Nolan revealed that they are no longer involved in Warner Bros.' DC Comics movie universe, after The Dark Knight trilogy and last year's Man of Steel. In a new interview with Time Out, Christopher Nolan himself revealed that he doesn't see himself returning to the superhero genre, but he doesn't rule it out entirely."I think I had a great experience with the superhero genre and got to explore a lot of things, but it was a good decade of my life and I find it hard to imagine returning to it.
