My apologies for the delay in addressing this topic, but I'm a little confused by what I'm reading in the posts above. Tired eyes and little sleep I fear, so I'm unsure if anyone actually thinks they are seeing the long-lost roadshow cut or not.
I can see no practical reason for an interval on a film that runs but 125 minutes, of course stranger things have happened, so anything is possible. In checking over a few online ticket sources and cinema listings, I see that this appears to be the, studio imposed, original release cut of 125 minutes.
The original 3 hours plus rough cut has never been released anywhere at any time and is not thought to exist in a complete form at this time. Wilder himself, sometime in the year preceeding his death, had indicated publicly in an interview that he doubted if the full print was still in existence anywhere, as he certainly didn't have it.
The last efforts towards reconstruction took place a few years back, two missing segments had been found, one that was audio-only with no visual image ("The Curious Case of the Upside Down Room"), the other video-only without sound ("The Dreadful Business of the Naked Honeymooners"), both of which were featured on the
Image Entertainment laserdisc release. Since that time, I have yet to hear, at least in Sherlockian circles, that any further progress has been made towards restoring the film to Wilder's original concept and running time. While I'm certainly not the be-all and end-all of Sherlock Holmes related information, something like news regarding a screening of the original cut of
PLOSH would be hard to avoid, so I'm fairly confident when I say that this is the edited and original theatrical release being shown. More's the pity really, as I expect the missing bits, particularly the flashback sequence to Holmes' college days, a sequence designed to add insight into Holmes so-called 'misogyny', might add much to the viewers understanding of what Wilder was aiming for and given the film a bit more substance. I, for one, would love to see the full version of what Wilder called the most elegant movie he ever made.
However, that being said, I'm envious as hell of anyone that will be seeing even this usual truncated version on the big screen, as the last video release ( I have yet to see the LD version) certainly doesn't do this thoughtful and extravagent film justice. Beautifully shot, wonderfully acted (watch for Clive Revill's magnificent scene-stealing role as the Russian ballet impressario..."Beeg dog from Bas-kair-ville" indeed!) and complemented with a maginificent soundtrack by Miklos Rozsa, I'd recommend seeing this if you get the chance!
While Mr. Lee's screentime is somewhat limited, this was a pivotal role in his career and went a good way towards presenting him as something other than mainly a 'horror film actor', both to the audience at large, and to casting agents. His commanding presence as Holmes' elder brother Mycroft, while not the least bit like the character presented in Doyle's stories (in the Sherlock Holmes stories he is grotesquely overweight and lethargic, but with a razor-sharp mind superior to Sherlock), his character is a key factor in the plot. The sequences that have him verbally fencing with the late Robert Stephens (whose son Toby is currently enjoying some success as a Richard Branson-like character, okay he's the villain, in the latest instalment of the Bond franchise -
Die Another Day) as brother Sherlock are particularly engaging. Another interesting side-note,
The Private Life of Sherlock Holmes also marks Mr. Lee's third performance as a different character in a Sherlock Holmes film, since he had previously appeared as Sir Henry Baskerville in Hammer's
The Hound of the Baskervilles opposite Peter Cushing as Holmes and as Sherlock Holmes himself in
Sherlock Holmes and the Necklace of Death (both of which can readily be found on Region 1 DVD).
Bottom Line: Go see this film, interval or no interval, in the cinema if you can, whether as a Christopher Lee fan, a Billy Wilder fan (and who isn't?) or a Sherlock Holmes fan, you will enjoy it!
For more on my personal take regarding
The Private Life of Sherlock Holmes, and more specifically Mr. Lee's involvement, I would humbly suggest visiting
