#2 - Truth Be Told
Prior to social media and the 24-news cycles, movie fans watched their characters' fates unfold before their eyes. When Luke Skywalker learned his father was the Sith Lord himself, Darth Vader, the Star Wars faithful's jaws dropped, screamed a collective "nooooo", then ran to tell anyone who'd listen.
Fun fact: In order to keep Luke’s father news under wraps from the public, cast and crew, George Lucas instructed David Prowse (Darth Vader) deliver the line, “Obi-Wan killed your father” while shooting the scene. Only later, during final production was James Earl Jones, the voice of Darth Vader, given the script – which he couldn’t believe himself!
