Re: Billing order.
The quality of this cast is just insane.
I cannot think of another movie with such a great cast. Even the Nolan Batman movies, or some of the 70s disaster pics, can't match this.
There is no Marvel/DC rivalry. Most of the great comic creators worked for both; Jack Kirby, Frank Miller, Grant Morrison, Walt Simonsen, Gil Kane, Steve Ditko, John Byrne, Steve Englehart, Mark Waid...even Stan Lee.
