I thought it was a very interesting show, they only had an hour to work with but I thought it offered a nice synopsis of Mark's career. Of course, SW got the most attention but the program succeeded in showing that while some people saw his career as stagnant after SW it was really quite the opposite.
I knew about the auto accident and its impact on ESB, but I didn't know about his connection to Eight is Enough. The first 12 minutes of the doc was pre-SW, and they even offered a few clips from his earliest work.
Interviewees included Mark's wife, daughter, brother, cousin, Annie Potts, Gary Kurtz, George Lucas, and Frank Oz. Pretty nice contributions, though it would have been nice to hear from Mark himself.
