The very first 'talking picture' version of The Hound of the Baskervilles, it had a budget of £25,000.
On February 28, 1931, Lustleigh railway station on the then-Great Western Railway, was used as the location for 'Baskerville' station at which Sherlock Holmes and Dr.Watson are seen arriving.
For many years, it was believed that only the (silent) picture negative of this movie still existed. However, in 1991, a complete set of negatives and soundtracks were donated to the British Film Institute (BFI) by the Rank Corporation. As such, the film now survives intact (and with sound) in the BFI archives.
