I heard that Boba Fett survived his “death” in Return of the Jedi (Episode 6). Is this true?
Yes, according to books, comics, and other sources approved by Lucas Licensing, Fett did escape the Sarlacc and went on to continue bounty hunting for many more years. George Lucas has said that in his own idea of the story, Boba Fett died in the Sarlacc. This is consistent with his usual position that the books, comics, and other stories are cool stories but not necessarily part of his personal vision of Star Wars. This doesn’t mean the stories from the books and comics are invalid or not correct – it just means that George Lucas considers the “Expanded Universe” (stories outside of the movies and TV shows) to be a separate story from his own vision.
