I saw the film only once. I missed the first part of it. I remember seeing this burly, scruffy, rough looking guy come into a pub and walk into a back room. As the man started to peal off various items, I noticed his eyes. After a few moments, I realized that it was, William Shatner. WOW! I loved it. For the rest of the movie, I couldn't wait to see what sort of disguise he would appear as. The China man in the end was choice.
I have always thought that it must be an actors dream-come-true to be able to play all of those wild and fascinating characters all in one movie.
I only wish that I could see it again, however, if I understood Mr. Shatner during an interview on Regis, there were no video version made for distribution. I respect that, but will never forget that movie.
