“As my mentor Hans Zimmer told me: You haven’t made it in Hollywood as a composer until you get replaced on a project. So I guess I finally graduated this week.
It pains me to leave the project, but a big thanks to Zack for asking me to be part of his vision, and I wish Danny, Joss and Warner Bros. all the best with Justice League.”
“Justice League” will be released to theatres on November 17, 2017.
