I know I'm somewhat behind the curve on this one but WOW! I love alternative history stories and this one looks to be fantastic. It taps into the classic Nazi/WWII 'flip the path of reality' concept used by countless writers while adding a fun 'what if' science fiction idea. It's as if someone read Philip K. Dick's 'The Man In The High Castle' and went in a slightly different direction.
I hope the finished film measures up to this trailer.
