The Oprah Winfrey Show

In an episode from early 1997, Oprah Winfrey welcomed C-3PO, R2-D2, Chewbacca, Darth Vader, and an Ewok to her stage, celebrating the Star Wars Special Editions. After that, Anthony Daniels and Peter Mayhew were brought on stage to discuss the making of the movie and its success. Even George Lucas joined in later on, albeit by satellite. The show wasn't focused on all episode, though. After the Star Wars guys left, there were segments on the making of Star Trek: First Contact, and several Superbowl commercials.
