He played Basil Hallward later on in his career, this role was filmed in 1976 and was shown in a the time slot for "the play of the month". However, he also played Doian Grey in the "Armchair TV Series" in 1956.
The reason it is not very well know is because it was a TV series that never made it onto DVD.
Oh my word, it's so funny there was made a mannequin of him. Yummy, naked Brett in shops :0)
Terry Manners wrote about the matter in "The Tortured mind of Jeremy Brett" (p. 89-90):
During this period Jeremy was the epitome of the seventies man. The vision of the typical Englishman to those who flew in from abroad was still a cross between Sherlock Holmes and a university don, wearing an old tweed jacket with a leather patch at the elbow, baggy trousers and maybe even mismatched socks. He would be a comfortable kind of man, a sort of lovable shaggy dog, perhaps a bit eccentric but someone you could depend on. He was personified at this time by people like actor Richard Briers, who would often be seen walking around London in a safari suit he had worn in a TV play. He liked it so much that he bought it.
But Britain had changed radically following the blaze of the sixties.
Jeremy was now talked about in the theatre world as the seventies thespian about town ... colourful shirts, cravats, flared trousers and battledress jackets. In fact he was such a fashionable, romantic figure in people’s minds that mannequinmaker Adele Roostein, who had already made window dummies of Twiggy and Lady Jacqueline Rufus Isaacs, decided that he had the look of the moment and convinced him to model.
Soon there were life-size copies of him in shop windows all over the world, and he even represented modern man in the Bath Museum. But the truth was that Jeremy never spent a bt of money on clothes. If he found something he liked he would fog it to death. Most of his cashmere sweaters had holes in them at the elbow and he still wore the suit he had taken his name from, which was given to him when he was seventeen. He boasted to friends that he bought a couple of pairs of trousers, three pullovers and four shirts each year and that was al!. ‘If you have just a tiny bit of flair you don’t really have to dress up,’ he said. The one fashion item that really did appeal to him was platform shoes. ‘I fall about and hit my head on doors,’ he said, ‘but they’re fun. Now I’m taller than all my three brothers.’
