Not only did we get to see Houdini, Bess, Sir Arthur, and Lady Doyle at their dinner table, but there's also footage of Howard Thurston, Horace Goldin, Max Malini, Carl Rosini, and Houdini on-stage magically producing their wives from a large cloth. Wow!
It's likely the production acquired this footage from a stock footage house. There are several listed in the credits. However, a search of their websites turned up nothing. It's also possible this came from the Doyle estate. Whichever the case, there may be more than what we see here!
I ran a moving picture, taken at the banquet, and if you desire a copy, I shall be pleased to let you have one. It is a remarkably good picture of Lady Doyle, and you have a very amused expression on your face as if you were in a good humor—and I hope you were!
- Houdini to Conan Doyle, June 1922.
If you missed the series, you can watch it for a limited time on the PBS website. The Houdini footage appears in S1 E3: Shadows and Sleuths. You can also buy the series on Amazon. For those in the UK, you can watch the series on the BBC iPlayer under the title Killing Sherlock: Lucy Worsley on the Case of Conan Doyle.
