Do British films have writers?

A big splash on the front of the Observer's Review section yesterday headed Brit flick fever declared that:

British movie-making is on a roll. From edgy revenge tragedies set in the Midlands to Bollywood marriages made in Bath, there is an unfashionable optimism about our film industry. We bring together 25 of the actors, directors and producers who are playing the leading roles in our screen revival.

Good news, of course. But do these films have writers?

There are none in their list apart from Annie Griffin, and that's because she's a writer-director.
