No spoilers! New 'Star Wars' plot cloaked in unprecedented secrecy

By Lisa Richwine LOS ANGELES (Reuters) - When actress Lupita Nyong'o showed up on the set of "Star Wars: The Force Awakens," many of her co-stars did not know what role she was playing. Newcomer Daisy Ridley was sworn to secrecy for three months that she had even been cast in the film. Walt Disney Co, which took over "Star Wars" with its 2012 purchase of Lucasfilm, scrapped the typical Hollywood practice of screening the movie for reporters before they speak with the cast.
