The best interview, as it is illustrated with backstage footage, remains "Slimy Piece of Worm-Ridden Filth - Life Inside Jabba The Hutt" which is a 20 minute filmumentary (based on a Skype interview) from Jamie Benning, and available on Vimeo here.
Jamie's filmumentaries are all worth exploring - the whole of The Original Trilogy, for instance, with embedded backstage material. Find them all here.
My work with mime, acrobatics and masks led to my working for Jim Henson on The Dark Crystal, animating large creatures. This led to my work on Jabba, in Return of The Jedi. Later I did some work on some other movies (see IMDb) including Labyrinth and Who Framed Roger Rabbit.
When I had a big website, full of family, work, autobiography, diaries, interests, etc - I was contacted by a fan / journalist, who asked if I would mind if he trawled my blogs and website to produce an entry for Wookiepedia. He made it, put it up, and it became editors' choice for a day. It has one or two 'errors' but I haven't corrected them.
It later migrated to Wikipedia (nothing to do with me, I assure you), so I have a larger entry than I really warrant. But I can't really change it, as Wiki etiquette forbids editing your own profile.
Nowadays, the same material wanders around and pops up in (say) the Muppet Wiki.
