I think guys like Joseph Kosinski and Rupert Sanders are in the Michael Bay, Zack Snyder, David Fincher camp of starting out in music videos and commercials where you have 30 seconds to three minutes to make something visually arresting. But nowadays where it's typical to see director jump from Cop Car to Spider-Man and Kings of Summer to Kong Skull Island, a director going from Halo commercials to Tron Legacy is what it is. Although there's an argument to made for Fincher starting with Alien 3, the poor experience had him starting small after that.
All that said, Snow White and the Huntsman already used imagery influenced by Princess Mononoke, so the guy managing to translate GitS visuals to live action isn't too surprising.
