When the "Old Man" who has provided "Chauncey" (Peter Sellers) with an home for most of his life dies, this erstwhile gardener finds himself homeless. Dressed in his finest handed-down suit and carrying his home in his suitcase, he emerges into the outside world without a clue. He has no money; he has nowhere to say, nothing to eat - he has no friends. He's like a full-sized infant whose only exposure to reality has been through the television. Luckily, he has a bit of a scrape with the limousine of "Eve" (Shirley MacLaine) and she takes him back to their palatial home to recuperate. She is intrigued by the simplicity of the man, but not so much as her father "Benjamin" (Melvyn Douglas). He is a sort of "Daddy Warbucks" character with huge wealth and equally extensive political influence - including with the President (Jack Warden). His and then their conversations with "Chauncy" are almost entirely carried out using nature as a term of reference. The planting and harvesting; the nurturing; the seasons; the good years and the bad - all of which resonate more with the millionaire as he begins to appreciate in far most basic terms those harmonies that are required to keep society - and thereby the more important economy - in synch. Meantime, as the benign influence of this man begins to grow, so does the affection for him from "Eve" and the curiosity in him from the security agencies who cannot find any information on this man. He doesn't even appear to have a birth certificate so is he really as pure as he appears or have the CIA been wiping records and not telling the FBI? Or vice versa? It's the expertly understated portrayal of an innocent character that Sellers delivers here that is both touching and thought-provoking. It challenges opinions, stereotypes and attitudes without overtly challenging anything. "Chauncey" invites us to look at our world through his eyes and that is quite revelatory be we saint or sinner. There is also a light-heartedness to this film that emanates not so much from deliberate comedy, but from the actions of a grown up untainted by cynicicm and who might prove to be the salvation many were - albeit unwittingly - awaiting. Though Sellers very much owns the film, Douglas serves really engagingly as his shrewd yet human counterfoil and with both MacLaine, Warden and Ruth Attaway's wise-cracking "Louise" supporting strongly, this is quite a poignant film about faith - in many of it's forms.
