The live "Man of Steel" disc promotional chat over at Yahoo! Movies was held this morning with Kevin Smith interviewing Zack Snyder, Henry Cavill, Michael Shannon and Amy Adams amongst others about the movie.
Zack Snyder did reveal some new concept artwork inspired by (not directly from) "Batman Vs. Superman" from artists Alex Pardee, Jonathan Wayshak and David Correia which he commissioned himself. The artwork can be won by fans who donate to the We Can Be Heroes charity.
In terms of actual news about "Batman vs. Superman", sadly there was none. A throwaway reference indicates Lex Luthor may be in the film, and Snyder would like Hans Zimmer back to compose, that's about it. Check out the artwork below, along with the full panel below:
