Yesterday the writer said that money now available for the channel to spend on other projects would be used to fund a small-screen adaptation of one of his most popular works, the 2002 novel Any Human Heart.

It will be made into a four-episode drama with a script written by the author, who was appearing in Edinburgh for the first time in 10 years.

Any Human Heart is written as the journal of the writer Logan Mountstuart, in the style of a autobiography, with appearances from real-life characters such as Virginia Woolf, Ernest Hemingway and Evelyn Waugh.

Speaking at the Edinburgh International Book Festival, Boyd said: “Now that Big Brother has been cancelled, I have been the beneficiary, and we are going to make a TV drama of Any Human Heart. We will start filming in the next few months or so, and it will be broadcast late next year.

“It’s fantastic news, I think it will be brilliant – but then I am the scriptwriter, and it is a fantastic and a rare opportunity to have a TV film made. I think, however, you really will see the difference between the novel and the filmed version.

“What you will get is only a small piece of the novel – just don’t go back to the novel and make comparisons.”

At the event, he read from his new novel, Ordinary Thunderstorms.
