Trench Cat

Hand over untold millions of dollars to Christopher Nolan to make an intensely personal dream project and you get an action moving rumination on collaboration and the process of movie making. Conversely, rope in Zack Snyder and he'll serve up burlesque brawlers in Burton drag twatting at Great War zombies and towering Brazil samurai in the virtual world of Mamoru Oshii's Avalon. Either approach is fine. No complaints here.
