I can imagine the conversation Christopher Nolan (Dark Knight Trilogy) had with the studio execs:
Execs: We’d really like to reboot Superman the same way you did Batman. Like for example a dark, gritty, realistic take on Richard Donner’s classic Superman 1 and 2 from the 1970s. Can you do it?
Nolan: How droll; been there done that. But can I recommend my mate Zack Snyder (300), he’s not as good (if I do say so myself) but he’s looking for a gig
Execs: OK, but can you at least take a producer credit? We’ll pay you a gazillion?
Nolan: Sure, why not?
