I'll not spoil it for you. The two best parts are the ending up the river, and when the Captain is explaining the evils and stupidity of books to Montag, in a secret library that they've just found and are about to destroy. It is interesting to watch the titles that Truffaut chooses to burn. The Marquis de Sade gets burned into ashes along with Jean Genet and Henry Miller. The movie was made in 1966, and the set design and props reflect that time.
Telephones are rotary, and have separate microphones and receivers, just as phones of that time did.
But they do have phones in every room in the house. They also appear to have widescreen televisions. There may or may not be a population problem of some kind. The movie is in English. It is Truffaut's only English-language film.
