Moviegoers may not be feeling superhero fatigue, but composer Hans Zimmer is. After scoring Christopher Nolan’s Dark Knight trilogy, The Amazing Spider-Man 2, Man of Steel, and now Batman v Superman: Dawn of Justice, Zimmer declared in an interview with BBC’s HARDtalk:

“I have officially retired from the superhero business … I did Batman Begins with Chris 12 years ago, so the Dark Knight trilogy might be three movies to you, to me it was 11 years of my life,” he said in part. “This one was very hard for me to do, to try to find new language.”

In addition to ending his long string of composing superhero films, Zimmer has taken a short reprieve from scoring films in general. Though he’ll be re-teaming with Nolan for Dunkirk, Zimmer told us during an interview for Batman v Superman that he’s going on the road for a while. Who can blame him after the daunting task of composing the music for the first live-action blockbuster to feature a clash of DC titans?

During our interview, he said of writing the Batman v Superman themes with Junkie XL:

For me it was doubly daunting because I’ve already done 11 years of Christian Bale and Chris Nolan Batman, and…This work keeps resonating in my head. I didn’t want to betray what I did in that time. You know, I didn’t want to go and belittle it or say, “Oh, this is all different,” or, “Forget about it. Let’s just start again.”

Zimmer isn’t the first to feel the burn. Joss Whedon, after helming The Avengers and Avengers: Age of Ultron, on top of consulting with the other Marvel filmmakers for various post-credits stingers and teases, is pretty much done with the MCU. Though, he did tease the possibility of coming back down the road. We’ll see how Joe and Anthony Russo (the duo behind Captain America: The Winter Soldier, its follow-up Civil War, and the two-part Infinity War) and/or Zack Snyder (who helmed Man of Steel and Batman v Superman, will helm Justice League: Part One, and is a producer on a number of other DC films) fair under similar pressure.
