Well perhaps not.
According a Snyder rep, a report this morning he is developing a Star Wars film that would be based on the Seven Samurai is not true.
“While he is super flattered because he is a huge fan,” states the rep, “Zack is not involved in any way with Star Wars. He is currently in post [production] on his two films, Man of Steel and 300: Battle of Artemisia.”
This doesnot mean that Snyder will never work on Star Wars, but being so busy at the moment, Snyder doesn’t seem to have the time to develop anything at the scope of a Star Wars movie.
