The team at HalloweenCostumes.com have put together a visual guide to the scum and villainy of the Mos Eisley Cantina. It’s pretty damn comprehensive.
This is a visual guide to the many colorful characters in Chalmun’s Cantina on that single day in year 0 BBY (Before the Battle of Yavin). Of course, in the real world, these characters were filmed over the course of several weeks in 1976: exterior shots in Ajim, Djerba, Tunisia on April 2-3 and interior shots on Stage 6 at Elstree Studios in Borehamwood, Hertfordshire, England on April 13-21. (A final set of close-ups was also filmed at Hollywood Center Studios in Hollywood, California in early 1977.) Our guide is based primarily on in-universe Star Wars canon sources and behind-the-scenes details. Any no-longer-canon “Legends” (formerly the “Expanded Universe”) sources are noted accordingly.
