I just read that AS WELL AS the actual streets of Los Angeles/Hollywood being transformed back to how they were 50 years ago, this movie has had
OVER 100 different individual sets built for it.
Many also think that this movie could be 3+ hours long as they're expecting a real "epic" of a story with so many intertwining characters and subplots.
I just hope it doesn't seem mish-mash and it's done properly. Would hate for there to be unnecessary characters or things just in "for the sake of it".
