Sherlock Holmes: The Man Who Disappeared from 1951 was a pilot episode for a TV series that didn't happen.
The Conan Doyle story gets the treatment nowadays approved by the Agatha Christie estate - pay the money, keep the title, and change anything you want.
In the beginning of the episode, a woman (Beryl Baxter) tells Hector Ross (Neville St. Clair) that he is wanted by someone - it sounds like he's being forced to do something and hasn't any choice but to comply.
Later, in Holmes' quarters, Mrs. Ross comes to report her husband as missing.
John Longren plays a balding Holmes - which doesn't matter because he wears the deerstalker cap with matching cape most of the time. He had a speaking voice similar to George Sanders - very appropriate. This Holmes, however, is different, as he breaks and enters and knocks people down the stairs.
My only question is, how dumb was he, since I had this figured out a good ten minutes or more before Holmes did.
A disappointment.
