A Star Wars legend is coming to SF for May the Fourth

• The special screening at the newly renovated Castro Theatre will feature a conversation with Daniels and Howard Roffman, a Lucasfilm veteran and vice president of the SFFILM board.
• Daniels donned the golden chrome suit for 11 "Star Wars" films, playing a prim and proper butler of sorts who nevertheless got caught up in the rebels' escapades alongside the cheeky companion droid R2-D2.

Fun fact: Having to wear the costume was such an unpleasant experience that Daniels nearly declined to return for "The Empire Strikes Back."

• The first iteration took two hours to put on and made it hard to move. Daniels described it as claustrophobic with no ventilation in his memoir, "I Am C-3PO: The Inside Story."
• Thankfully for his fans, he reprised his role — Daniels is the only actor to work on all 11 films and has voiced the character in several animated TV series.

The big picture: May 4 has become known as the unofficial Star Wars Day, a play on the series' catchphrase, "May the force be with you."

• The fan-created event's exact origin is unclear, but it has since spun out around the world and become an annual celebration in the Bay Area.

What's next: Tickets are on sale now for SFFILM members. Sales for the general public kick off Friday.
