If you haven't yet gotten this set, I'd make every effort to do so NOW. Amazon's Marketplace is still a good bet for new and used copies. While Houdini's movies are all now available on multiple DVDs and streaming, this set contains a wealth of archival footage of Houdini's escapes that doesn't exist anywhere else. It also includes The Grim Game plane crash footage, and several minutes of Houdini's very first film, Merveilleux Exploits du Célébre Houdini à Paris (although the set doesn't credit it as such).
Thank you Dorothy and Dick.
