Zack Snyder had a tough gig ahead of him when it came to making the second reboot of the Superman franchise, since Brian Singer’s Superman Returns didn’t win audiences over quite so much. (Though our resident master Josh Tyler loved it.) But everything Snyder does is given a weary glance when it’s first announced. But when you’re somebody as iconic as composer Hans Zimmer, there’s a much different kind of anticipation involved, especially after his masterful work for Christopher Nolan’s Batman trilogy. Would you be surprised to know that the man himself was even a little nervous about the gig?
