1963 British film by George Pollock
Murder at the Gallop (1963) is the second of four Miss Marple films made by Metro-Goldwyn-Mayer. It was based on the 1953 novel After the Funeral by Agatha Christie, with Margaret Rutherford as Miss Jane Marple, Charles "Bud" Tingwell as Inspector Craddock and Stringer Davis (Rutherford's husband) as Jane Marple's friend Mr Stringer returning from the previous film.
It also stars Robert Morley and Flora Robson and was directed by George Pollock, with James P. Cavanagh credited with the adaptation. The music was by Ron Goodwin. The film's location shots included Amersham, Little Marlow and Hilfield Castle. It is a sequel to Murder, She Said and was followed by Murder Most Foul and Murder Ahoy!, all with Rutherford as Marple.
The film changes both the action and the characters. The original novel featured Hercule Poirot rather than Miss Marple, and Christie's trademark suspense is seasoned with light comedy. Miss Gilchrist from the original novel has also morphed into Miss Milchrest.
