Thanks to a leaked companion book for Batman v Superman: Dawn of Justice, we have some new photos and additional insight into the film and its characters. They examine the origin of certain elements of the film such as Alfred, the Batcave, Batman's armory, and even the Batsuit that Bruce Wayne wears.

Zack Snyder made a few changes to Batman’s backstory with this film. For example, Alfred (Jeremy Irons) is not the loyal Wayne family butler that we know. His backstory was altered so that he was actually the Wayne’s bodyguard, and he is the only member of the Wayne Manor staff that Bruce kept on board after his parents were killed.

The book also confirms that Lauren Cohan is playing Martha Wayne, alongside Jeffrey Dean Morgan as Bruce’s dad, Thomas Wayne. In this version of Batman’s story, the person who murdered Bruce’s family was never found.

Batman v Superman hits theaters on March 25th.
