The Making of Star Wars
Vanity Fair takes a look inside the photo-heavy book "The Making of Star Wars: The Empire Strikes Back". Lovely!

"What has become an iconic photograph of Hamill, George Lucas, Fisher, and Ford (in the background are chief hairdresser Barbara Ritchie; Michael J. Duthie, an editor who happened to be visiting the set that day; and assistant to director Debbie Shaw, daughter of actor Robert Shaw)."

"Harrison Ford sitting behind an X-wing."

Mark Hamill

"At the dining-room door, unit publicist Alan Arnold, director Irvin Kershner, Ford, Carrie Fisher, and Billy Dee Williams."

"Phil Tippett and Jon Berg stop-motion animate a shot with all three walkers (the background walkers are cutouts). Originally the plan had been to photograph the walkers against four-by-five Ektachrome transparencies shot in Norway; when these didn’t work as planned, matte artist Mike Pangrazio copied select Ektachromes onto large scenic backings."

"When Darth Vader (David Prowse) revealed his secret to Luke, Hamill was hanging onto a pinnacle above mattresses placed on cardboard boxes about 30 feet off the ground."

"The opening crawl was filmed at Industrial Light & Magic, circa March 1980."
