Lord Fellowes - Baron Fellowes of West Stafford, as we should properly call him - began by saying that the breakthrough in his career had come when the director Robert Altman asked him to work on a country-house murder mystery (but 'a whocareswhodunnit, rather than a whodunnit'), set in the 1930s. This film was Gosford Park, the forerunner to Downton Abbey, which was to earn its writer an Oscar for Best Original Screenplay and change his life. Before that, Julian Fellowes has described himself as 'a fifty-year-old fat balding actor', who had once waited for hours by the telephone to find out if he'd been cast as replacement dwarf in Fantasy Island. Now, post-Gosford and post-Downton, directors are beating a path to his door and he can hardly have time to breathe. A fourth series of DA has just been commissioned and there's the Christmas special to write; I read elsewhere that a series on English country houses fronted by him for ITV is in the pipeline, and that he's working with NBC on a programme about the American elite.

He also told us a wonderful story about Robert Altman wanting to cut one of the best lines of all in Gosford Park (delivered by Maggie Smith, of course), in which she tells the movie producer that he needn't worry about giving away the denouement of his latest murder mystery 'because none of us will ever see it'. Apparently the very idea of anyone not wanting to watch a film was so upsetting to Mr Altman that he could hardly bear to include the line; Dame Maggie had to persuade him she could somehow 'make it work'.

So what else did we learn? His wife, Emma, is his first script-reader. She is the person who suggested making Bates the valet, lame - which raises a host of interesting questions. Why would Lord G employ a handicapped servant? What is their past history which makes the one indebted to the other? (Questions that, unless I missed a crucial moment, the series has yet to answer...) Also, he reads every word of the script out loud, which shows him the repetitions that need to be deleted and whether the dialogue will work. And as to the secret of Downton Abbey's success, he believes it is because Downton is 'inclusive'. Everyone has their story to tell, from Daisy the scullery maid to Lord G himself, and each story carries the same weight.

What's the question you would have asked Lord F, had you been there? (And just so you know, he won't say anything about future plot developments...)
