Acting for Two: Richard Greene plays both Sir Henry and Sir Hugo (even though Hugo is supposed to look like Stapleton the producers thought this would spoil the movie.)
Billing Displacement: This the only Sherlock Holmes film where the actors playing Holmes and Watson did not get top billing. Richard Greene, the actor who played Sir Henry, got the top bill. Basil Rathbone got second billing and Nigel Bruce got fourth billing.
Playing Against Type: Basil Rathbone was best known for playing villains before he was cast as Holmes. Sadly, however, playing Holmes would doom Rathbone to typecasting again as he could never be associated with anything but Holmes after this.
The Cast Showoff: Dudley Moore plays the piano in this film. In real life, Moore was an accomplished concert pianist, and often on movie sets would entertain the cast and crew by playing the piano.
Creator Backlash: Terry-Thomas described this as "the most outrageous film I ever appeared in...there was no magic...it was bad !".
1982 serial
Creator Backlash: Tom Baker himself came to consider his performance a failure saying: "I couldn’t lift the character into that special world that makes Holmes so funny and fascinating." He later claimed that The BBC apologised for both the production and his performance.
He didn't want to harm Nicholas Woodeson, who was playing Sir Henry Baskerville. In fact, the bloody dog had fallen in love with Nicholas. Someone had the notion of hiding sausages under the lapels of Nic's dinner jacket, but it was of no use: The dog actually appeared to be blowing kisses at Nic. And then, a member of the camera crew suggested that, 'why didn't we throw Nic at the dog, and then run the film backwards?' Nic Wilson was not amused, but I was. I laughed so much, I hoped that the joke was what I'd been waiting for all these years before I died.
Other adaptations
