Like threads of recovered memory, I still think from time to time about this movie, although more than thirty years passed since I saw it on TV.
What happened at the racetrack? What was the trigger for the brainwashed driver? What was the significance of the monkeys? What was the motivation behind the bad guys' plan? In fact, who were the bad guys? How much of this was written by L. Frank Baum?
In my memory, this movie is surreal, powerful, full of intrigue -- but it is not explicable. It cannot be pieced together from those threads of memory. I would welcome the chance to view it again, through adult perceptions rather than the prism of adolescence. It could be a disappointment, of course. But I believe Bruce Geller (Mission: Impossible) was involved in this TV movie, and the original MI episodes hold up quite well.
Before playing Dean Wormer in Animal House, John Vernon was consistently excellent as a heavy. This movie -- if we ever get to see it again -- is from those times earlier in the 70's.
