The Universal Studios attraction was a “$3.75 million production featuring state-of-the-art, never-before-seen laser and pyrotechnic special effects, combined with the skills of actors, magical illusions and computer-coordinated animated characters.” I never got to see it, sadly. I went to Universal Studios once or twice, before 1983, and remember only the Jaws and Battlestar Galactica rides.
The fire-breathing dragon sequence in the Conan Spectacular was inspired by the climactic scene in Sleeping Beauty (1959). I’d forgotten how scary the original Disney classics could be. Not only is the battle convincing and way ahead of its time conceptually, it’s one of the earliest screen examples of the sword and sorcery trope.
