Silver Blaze

Silver Blaze is a 1937 British black-and-white crime mystery film, based loosely on Arthur Conan Doyle's 1892 short story "The Adventure of Silver Blaze". It was directed by Thomas Bentley, and was produced by Twickenham Film Studios Productions. It stars Arthur Wontner as Sherlock Holmes, and Ian Fleming as Dr. Watson. In the United States, the film was released in 1941 by Astor Pictures, where it was also known as Murder at the Baskervilles, retitled by distributors to capitalize on the success of the Basil Rathbone Holmes film, The Hound of the Baskervilles.
