Does anyone remember what the anticipation was like?
Yep. In February 1982, we had a "Star Trek" convention in Medlow Bath, Australia, and a club member with Japanese ancestry brought along a copy of "Super-Visual", a gorgeous Japanese language book that was actually Volume 3 in a series, and this book covered TOS Season 3, Filmation's TAS, TMP and featured the first several publicity pics from "The Wrath of Khan": Kirk, Spock and McCoy in the new maroon uniforms (we were reminded of Canadian Mounties) and our first glimpse of then-unknown, Kirstie Alley, as Lieutenant Saavik. "Super-Visual" managed to scoop "Starlog" by many months! Our friend translated all the captions. Imagine 15 or so fans surrounding one magazine, oooohing and aaaaahing.
Rumours were rampant. I was lucky that Paul Winfield happened to be in Sydney, filming a movie, and I scored an interview! He actually confirmed the rumour we'd heard about an impromptu scene, of Terrell rolling down a sand dune, having to be abandoned because the only available stunt guy was put into blackface.
(See the top left pic in the third double-spread in the "Fantastic Films" pages above.) Terrell and Chekov were to get startled by a child's face at the porthole of Khan's cargo bay dwelling.

He also mentioned that Saavik and Kirk got along much better that Alley and Shatner. We were confused by this, until we finally saw ta penpal's tape of the US ABC-TV version of ST II, with the alternating closeups of Saavik and Kirk in the elevator (instead of the wider two-shot, used in all other versions of the film), and it appears they are flirting with each other.
Official, licensed books and magazines could often take three months (sea freight) to arrive Down Under. There were rarely local printings, so we always kept watch. One collectibles shop got in three copies of the "Starlog" movie magazine a few weeks before our (delayed) premiere, so using the stills in that, a group of us convinced one of our Mum's to make uniforms, another knitted the collars, I made insignia badges (out of ice cream containers painted gold) and the felt sleeve and shoulder trims for each uniform. (The Saturday morning before the gala premiere, we were granted free tickets to a preview, which gave us an additional chance to tweak our costumes! One person won the novelisation, not yet in shops, which was taped underneath their chair. So jealous!)
