Apart from a rare screen appearance by Sir Gerald du Maurier, the only point of interest is that it was produced by Alfred Hitchcock . Script adapt . Austin Trevor's third and final attempt at being Hercule Poirot on screen is not a great success. The film lacks the style and the energy necessary to bring off a good whodunit. It would be over thirty years before anyone attempted Poirot on screen again.
Script adapt .
Not a bad film, and the cast list is a veritable Who's Who of British supporting actors.
