I cannot get your video to play, but HBO is currently running a documentary about him called "Bobby Fisher against the world".
I have watched it and it is a very well done story about his youth, that match vs Spassky, and his mental state as it deteriorated.
You are correct about Spassky bending over backwards to accommodate Fisher's demands, and I think it was remarkable it even took place considering how difficult Fisher was to deal with.
A clip from the HBO documentary. I assume your link is a different film but perhaps not?
