Hans Zimmer and Junkie XL composed the score for Batman v Superman: Dawn of Justice, and only Junkie XL was attached to work on music for the upcoming Justice League. With Zack Snyder leaving the project, however, it looks like someone else will be taking the musical reigns for the project.
According to the Hollywood Reporter, Danny Elfman has now signed on as composer for Justice League. As some of you may know, Joss Whedon has now taken over Snyder's responsibilities during post-production, and he had Elfman help him with the score for his last movie, Avengers: Age of Ultron.
Elfman will be working with the original scores and leitmotifs that were introduced in BvS by Zimmer and Junkie XL, so there's probably still some credit going to both of them. As of now, Junkie XL has moved on to work on the Tomb Raider reboot, and he had this to say about Elfman taking over:
I actually really like the music that was put into Batman v Superman, and I think Zimmer did an splendid job when it came to replacing John William's Superman theme with his. Wonder Woman's theme is also pretty kickass, but I guess I haven't been able to properly point out which is Batman's theme.
Did you know that Lex Luthor's theme is Superman's played backwards and distorted? That's musical poetry for you.
Justice League comes out Nov. 17.
