I just recently re-read it because I did a little interview with the guy who played the murdered brother. It was a couple days work 40-something years ago so he didn't remember too much, but he did give me a couple small anecdotes that were fun. Like the fact that the "blood" which covered him (heavily) was chocolate syrup and he had to look like that all day ... which was okay ... for a little while. Then for the rest of the day he found himself surrounded by every fly on the Universal lot!
