It took two years to get all the effects right.

We photographed a lot of the material a dozen times for approval. Every night we�d run [it for] Roddenberry and he would say �yeah, let's have this � faster and smaller... A little bigg a little different�. He was very critical, but he was also real right in what he wanted.

As it eventually turned out, everything that we were able to achieve for him, the flights, the movement of the stars and of the ship and the transporter shots, all of the exotic work that was involved in visual effects at that time and that was really a very primitive era � back in the �60s, there had been very few visual effects shows that had any quality that was up to what he was expecting on Star Trek.
