Its Spielberg so of course the look will be perfect. Plus Lewis will be great.
Only question here will be script/story. Quick check I see its written by the guy who wrote Munich. I loved Munich, very intense, gritty, and realistic.
So we got Spielberg Director/Producer so everything should be perfect. All the costumes/sets/etc will be spot on. Lewis, one of the best if not the best working today. And finally a solid writer too. Sounds like a contender for film of the year. Although, the early buzz for Killer Joe and The Master sounds like they are going to be tough to beat.
Looking forward to it.
