You're in for a real treat! I consider this film a comedy film noir, but serious enough for the viewer to enjoy a good crime-mystery. This film has a few twists to it. Just when you think you know who the killer is, SURPRISE, they gotcha. There is plenty of fun and adult humor along the way. There is an excellent all-star cast here to enjoy: Alec Guinness, David Niven, Maggie Smith, Peter Sellers, Richard Narita, James Coco, James Cromwell, Eileen Brennan, Peter Falk, Nancy Walker, Estelle Winwood and Elsa Lanchester. If Truman Capote seems to be a little, well...different. Well, you've guessed something else, unintentionally. Yes, Truman Capote, respectfully, lived a different lifestyle. He was gay. He played "Lionel Twain" and made it a memorable performance. Maggie Smith is such a delight in this film. Sometimes I will watch this film again just for her comedic preformance. Her delivery of lines is perfect. David Niven always a class act. Peter Falk wears a trenchcoat again, which of course reminds us of his "Lt. Columbo" character which over thirty years now he is still playing on television in brand new tv-movies. It's neat to see Eileen Brennan in a good, funny role. Nancy Walker has a gem of a role. We remember her in the film, "Best Foot Forward" and the tv series "Rhoda". On this DVD version is a ten-minute conversation with Neil Simon about the casting and the making of "Murder By Death". What would have been nice is if they would have had a cast reunion for audio commentary or on-camera interviews. If you liked "Murder By Death", you might like the follow-up The Cheap Detective (1978). Peter Falk, Eileen Brennan,James Coco and James Cromwell are also showcased in this film with another different all-star cast. There is also another film simular to , but not as good as, "Murder By Death" called "Clue" (1985), based on the board game. This film also has an all-star cast, including Eileen Brennan.
