By Carl Slaughter: Before Twitter, before convention panel discussions, actors got on The Tonight Show to share engaging stories about their time on the set and their time on the promotion trail. On his first Tonight Show appearance in 1977, Mark Hamill shared stories about George Lucas, Harrison Ford, Alec Guinness, the C-3PO actor, and Amy Carter. Including:

• Alec Guinness outpranking the set’s most notorious prankster, the man inside the C-3PO outfit.
• Giving a Storm Trooper helmet to Amy Carter at the White House and telling her to wear it during dinner.
• Being forced to read this line: “Fear is their greatest defense. I doubt if the actual security there is much greater than on Appalyer-Sullust and what there is is most likely directed towards a large-scale assault.”
• Harrison Ford threatening to tie up George Lucas and force his to read his own tortuous script lines.

(I heard it was Carrie Fisher who threatened to tie up Lucas and make him read this line, “I thought I recognized your foul stench when I was brought on board.”)
