I'm 52, and, along with my younger sister and brother, saw this movie, when I was a kid. It remains one of the funniest movies I've ever seen, and I've seen an awful lot of movies. After seeing it the first time, and literally screaming and crying with laughter at much of it, my siblings and I would search the TV Guide as soon as the magazine arrived at our house hoping to find Murder He Says among the listings for the coming week. Once or twice a year, we would be beside ourselves with glee to find it. It was an absolute treat for us.
Many of its scenes are indelibly etched in my memory: Fred MacMurray with Grandma; the scene at the large, lazy-susan dinner table, with everyone trying to move the table one way or another to get the poisoned food away from them; the scenes in the basement toward the end of the movie, and, especially, the scene when Fred MacMurray is caught in the basement coal bin by Bonnie Fleagle (unquestionably, one of the funniest scenes in movie history.
It's a movie that is both frightening and extremely funny. Directed by George Marshall, who also directed several other favorites of mine: Destry Rides Again (Jimmy Stewart and Marlene Dietrich; a 1939 classic); Fancy Pants (Bob Hope) and The Mating Game (Tony Randall, Debbie Reynolds).
Yes, it's improbable and, I'll grant you, silly. It is also, IMHO (in my humble opinion) a great movie. Yes, great...so there!!
