Basil Rathbone and Nigel Bruce star in this 1939 adaptation of Sir Arthur Conan Doyle's frequently filmed novel, and the result is one of the most atmospheric and purely enjoyable versions of The Hound of the Baskervilles. Except for minor changes, the script is true to Doyle's enthralling mystery about a centuries-long curse against heirs to the Baskerville estate, situated within the haunting and deadly Dartmoor in the southwest of England. With the arrival of a new master, Canadian Henry Baskerville (Richard Greene), Sherlock Holmes (Rathbone) and Dr. Watson (Bruce) are called upon to solve the strange case of the "gigantic hound" that may be readying to savage the poor fellow. Wonderful sets, crisp performances, and Rathbone's accessible but no-nonsense take on the Great Detective make this a real delight. Typical of the 20th Century Fox Holmes pictures, there's an in-joke, a final line of censor-defying dialogue alluding to Holmes's little problem with cocaine. --Tom Keogh
