I love this film. Don't want to give any of the good parts away, but Peter Sellers in Chancy, the...well, slow gardener for a rich old man, who's knowledge of the world comes from television. When the man dies, he has to leave the house, and make it on his own. The first time I saw it was in Sociology class, because there is a lot of commentary in it about the social class structure, as well as televisions affect on our society. The end is ripe for interpretation as well.
Chance wears the clothes and homborg of the old man (his former employer) and due to his appearance and quietness, he becomes a focal point mirror for everyone else's assumptions and views as he becomes integrated into upper class society through a comedy of errors. This was rated a four-star flick.
A few spoilers below if you're NOT going to see the movie:
"A simple-minded gardener named Chance has spent all his life in the Washington D.C. house of an old man. When the man dies, Chance is put out on the street with no knowledge of the world except what he has learned from television. After a run in with a limousine, he ends up a guest of a woman (Eve) and her husband Ben, an influential but sickly businessman. Now called Chauncey Gardner, Chance becomes friend and confidante to Ben, and an unlikely political insider."
