Sherlock Holmes and Dr. Watson investigate after being told an heir's estate is plagued by a ghostly dog.

The brilliant, secretive and volatile Sherlock Holmes faces his greatest challenge...An ancient family curse, a desolate moor, a spectral hound, a deranged killer on the loose and events threatening to spiral out of control---The Hound of the Baskervilles is the most celebrated Holmes story of all, a masterpiece of mystery, suspense and terror.

PBS Masterpiece Theatre's 2003 summary of the film: This chilling, star-studded adaptation of Sir Arthur Conan Doyle's tour de force presents Holmes and Watson as the author originally conceived them: vigorous men in their mid-30s, and the film has a relentless pace to match. Richard Roxburgh (the Duke in the Oscar®-winning Moulin Rouge! (2001)) stars as the mercurial Holmes with Ian Hart (Professor Quirrell in Harry Potter and the Sorcerer's Stone (2001)) as the contemplative Dr. Watson. The film also features John Nettles as local physician Mortimer, Matt Day as Sir Henry Baskerville, Richard E. Grant (Gosford Park (2001)) as the archaeologist Stapleton and Neve McIntosh (Gormenghast (2000)) as Miss Stapleton. The hell-hound itself, a truly terrifying beast, is brought to life as never before with state-of-the-art, computer-generated special effects.
