H2 (formerly History International) will air the documentary Houdini: Unlocking the Mystery twice during the day. Is this HISTORY looking to generate interest in their Houdini miniseries? Could be.
Houdini: Unlocking the Mystery first aired on Halloween in 2005. Hosted by Lance Burton, the documentary highlights footage from the 2004 Great Houdini Auction in Las Vegas, and includes rare interviews with George Hardeen and Anna Thurlow.
Houdini: Unlocking the Mystery is available on DVD. But if you haven't seen it, be sure to check out one of the showings on the 4th. In my opinion it's one of the very best Houdini documentaries.
UPDATE: Well, this is a 94 min. doc and it was slotted, at least on my cable service (Time Warner), as being only 1hr, so my TiVo didn't record the whole thing. Not a big deal because I have the DVD, but I hope this didn't happen to anyone who hadn't seen the doc. Gotta love cable!
