I watched these three 25-minute plays as a child (in black and white - it was a surprise to me to find out they were made in colour!), and enjoyed them then and when I saw them again recently. Alun Owen really was a great writer. The best story is definitely the first, McNeil, which features a barnstorming performance from Sean Connery as a barefaced and shameless liar. In the second, Cornelius, Michael Caine seems to deliver another take on his Alfie Elkins persona, as an office lothario becomes the butt of a rather cruel joke. The third play, Emlyn, starring Paul Scofield as an apparently successful barrister, seems a little strained, as you have to believe that the protagonist wouldn't wonder why her older lover is apparently single. Anna Calder-Marshall is very watchable throughout, even though the wardrobe people decided to make her a bit frumpy at times. Incidentally, I was also surprised at a rather unintentionally amusing introduction to each play by Laurence Olivier, which I don't remember seeing in 1969.
Once again, we have to be grateful to the Network DVD company, who have prevented yet another treasure from gathering dust in some TV company's vaults.
