Via Hollywood Reporter. I figured this was the best forum for the news, but could a mod mirror this to the anime forum? Mr. Kasdan seems quite notable, having written the screenplays for Return of the Jedi and The Empire Strikes Back and Raiders of the Lost Ark. Needless to say, his credentials are impressive. According to The Movie Blog a "relatively unknown guy" named Craig Zahler was once assigned to the script, so this seems to be a big step up and an indicator that the project is being taken more seriously.
