Not strictly manufactured in Britain, but made in Britain; the UK makes some of the best TV and films (movies) in the world. A recent good example of great British TV is the BBC drama Parade’s End starring Benedict Cumberbatch. In the dying days of the Edwardian Empire, Christopher Tietjens enters into a destructive marriage with the beautiful but cruel socialite Sylvia. Based in the novels of Ford Madox Ford.
In films, a good example of great British film making (well perhaps strictly speaking Anglo-American-Japanese film making) is the Bond films (based in the character created by Ian Fleming and starring Daniel Craig as the most recent incarnation of James Bond), the latest of which is Skyfall which is premiered in London tomorrow.
