I love Arena, but every time I watch it and hear Spock say "hot pursuit", I laugh. It just seemed so out of place.
We've discussed this before, but Kirk had just used the expression "hot pursuit" a minute earlier, in his log entry, so Spock may have been riffing off him. (Do Vulcans riff?)
-Any time they use the "soft focus" for a close-up of a woman (except perhaps when illustrating the effect of the Venus Drug).
-Any time Kirk says "sabotadge."
