James Earl Jones used his Darth Vader voice on the CB while traveling across the country:
You’re never tempted to pick up the phone and pretend to be Darth Vader? I did that once when I was traveling cross-country. I used Darth as my handle on the CB radio. The truck drivers would really freak out — for them, it was Darth Vader. I had to stop doing that.
Mostly, I think it was his declaration of their patrimony that was so dispiriting.
