I've been looking for this clip for, well, about 20 years. This interview was two years after Back to the Future and a bit before Crispin Glover was dumped out of its sequels. As I recall, the interview up until this moment was weird and banal, but then it became just weird.
What's most unsettling is how tame this meltdown seems to me now, in this age of constant coverage and effortless dissemination. At the time, though, it was shocking. Without precedent.
