We went to see it when it opened in Merritt Island FL; I had been working for a NASA contractor for a couple of years.
We got our son out of his kindergarten class a bit early* to get there in time. He'd been sleeping in our car when we saw
Trek III at the drive-in, and we'd had to leave him with his aunt when we went to see
Trek II, but now he was old enough.
We got there early. There were a few fans in homemade Starfleet uniforms there. The theater was unusually warm. One of the uniformed trekkers went to complain to the manager. He came back, telling us that the AC system was busted. "Just pretend you're on Vulcan," he said, handing out some passes that the manager had given us in compensation.
As the showtime hour approached, you could hear one digital wrist watch after another beep its tone in nerdley fashion, but it was
my own watch's chime that seemed to start the projector. You see, on my job I had a desk in a corner of a launch support complex, directly facing some big, impressive IRIG time display. With that as an example, I always set my watch
very precisely.
Oh yeah, the movie. We enjoyed it. It was about all you'd want from a Trek film that was also a holiday film. (The air conditioning
did come back after awhile.)
*I remember when were planning to see the film, I mentioned to my wife that we'd have to get the kid a half-day excuse (not a whole day, as he had otherwise perfect attendance), and wondered if we could write to DeForest Kelley and ask for a Doctor's excuse. Didn't follow through on that.
