The Hound of the Baskervilles (1939) is not just a classic but is likely the classic, classic Sherlock Holmes movie.
It is the debut movie of the most iconic Holmes on screen of them all, being Basil Rathbone. That is to say the greatest of all time, and its place in the classic film noir story.
Historical and faithful, wonderful and trend-setting, and with a noir-themed foggy soundstage, in an era just before World War, expressing the accumulated sophistication of the movie making of the 1930s, with more to commend it than simply its being a pure and fun expression of the Holmes story, as well as being the first of 14 films, which came to type a legend into the annals of cinema, drama, and noir.
Out on Fox's enormous back lots, the landscapes of Devonshire came to life and notably there was no hint at all with any participating artist, producer nor technician, no suggestion that there would be any more Sherlock Holmes films after this one.
After landing the role, Basil Rathbone said:
"I think that Holmes is one of the greatest characters in fiction. With all the thousands of detective and mystery stories that have been written since, the name of Sherlock Holmes still stands at the head of the roster of famous sleuths. It is synonymous with the very word 'detective'. To play such a character means as much to me as ten Hamlets."
