I’ve just finished The Big Screen, David Thomson’s history of the movies. Over 500 pages, but it slipped past like a dream. It goes on the shelf alongside Have You Seen? ( A thousand one-page reviews of individual films) and his Biographical Dictionary of Film, which would definitely be my desert island book. He knows so much, has seen so much, yet remains totally fresh, opinionated, witty – a joy to read. By comparison, everybody else’s comments on films just seem that bit duller, as though they’re not really trying.
