Word of the Day Challenge: Team
That is Sherlock Holmes and Dr Watson as played by Peter Cushing and Andre Morell in the 1959 Hammer Film adaption of Hound of the Baskervilles. It is a solid adaption with several liberties taken with story, one of which improves the way the villain is uncovered. Christopher Lee guests as Sir Henry Baskerville and Frances de Wolf and Ewen Solon have significant roles.
I strongly recommend this to fans of Hammer and Sherlock Holmes.
