Hans Zimmer has announced that he will no longer be writing scores for superhero films. Zimmer definitely won't be retiring altogether, so not to worry, folks.
Zimmer said, "I have officially retired from the superhero business. I did Batman Begins with [Christopher Nolan] 12 years ago, so The Dark Knight trilogy might be three movies to you - to me it was 11 years of my life."
Not only did he compose for that trilogy, but he also did for Man of Steel, as well as Batman v Superman: Dawn of Justice.
