Have you seen GM Bobby Kim's movie the "Manchurian Avenger"? Sr. GM Sereff has a bit part as do lots of USTF guys. In one part they are doing an ITF pattern. Bill Wallace has a big role with few lines. When I was at one of his seminars I asked if he had troubel learning his lines for that part. He just grimaced.
I've seen it, but don't have a copy. I do have a copy of Kill Line though. Another fine example of the genre.
