There have been a host of Houdini documentaries over the years. This one is a fun documentary because it features Doug Henning and Harry Blackstone Jr.. I'm sure it's somewhere on youtube, but I didn't see it. Granted I didn't look through all the pages of documentaries.
This one is kind of unique because you can watch it on the site but you can also read the transcript, which is not something that most sites offer. It's a pretty standard documentary for the most part, no big revelations or anything. But as I said, some great footage of two of the recent masters of the art besides ton of Houdini stuff. This was originally shot for the Wisconsin Public Television out of Madison WI. It originally aired in April of 1987.
