The "Fox" (rex harrison, a couple years after My Fair Lady) invites his ex girlfriends to visit. and this will require the assistance of an assistant, who can be relied upon, and is willing to tell some lies in the process. he hires McFly (Cliff Robertson) to help him play a huge trick on the ladies: her highness (capucine), Bunny McGill (edie adams), and the feisty Mrs. Sheridan (susan hayward). They are all lured there with the idea that someone is dying, and will leave a huge fortune to one of them. Mrs. Sheridan has a nurse, or assistant, or something... played by the awesome Maggie Smith. so the ladies all spend the next couple days arguing over who has the most right to the fortune. lots of talking. and some shenanigans. mayhem. some twists and turns. a couple gay references. directed by joe mankeiwicz. story by Thomas Sterling. his only novel. which itself, was based on the 1606 play Volpone (Fox!) by Benjamin Jonson, according to wikipedia dot com. it's quite good. the actors mostly yell and snarl at each other. Maggie Smith was great as usual, and the story is fun to watch as it unfolds.
