Someone once asked me this question: "what's a fact about Star Wars that no one knows". I replied "Chewie has the last line in A New Hope" and then everyone froze and quickly went to their phones to look it up on YouTube.
Peter Mayhew sadly passed away at the age of 74 a few days ago but the news just surfaced. You can read a statement from his family that they posted on his twitter.
We'll miss you Chewie.
