The Norman Conquests

The 1977 TV adaptation of the trilogy of comedy plays that appeared on the London and New York stages. http://en.wikipedia.org/wiki/The_Norman_Conquests. Starring Richard Briers, Penelope Keith, Tom Conti, Patrick Troughton, Fiona Walker and Penelope Wilton. Here's a review from someone in Australia I found on the IMDB site:

The Norman Conquest trilogy is a most satisfying set of tales, in which the events of one week-end are told three times, set in different rooms through the eyes of different characters, none of whom has the whole picture. The script (Ayckbourne) is witty, the ensemble of actors clicks, and the characters they play are well defined and interesting. Tom Conti, as the pivotal character, exuded the charm and charisma that were subsequently lost in Hollywood; Richard Briers and Penelope Keith were at the top of their "Good Life" form; and David Troughton was marvellously lovelorn as the vet. See the three episodes. You won't regret it.

Before the complaints start coming in, I'll let you know that episode 1 is 1 hour and 33 minutes long, episode 2 is 1 hour and 45 minutes long, and episode 3 is 1 hour and 48 minutes long. That's over 300 minutes of video on the disc. Nobody is being ripped off.
