I found a very brief article from 2002, after the release of Last Orders, in the Times.

Almost Famous by Hilary Rose 05-04-2002

Michael Caine described J. J. Feild as "a lovely guy who not only is a great actor but better looking than me so therefore a good double", which is handy because 24-year-old Feild played the younger version of Caine's character in Last Orders (and Frank Cheeryble in last year's BBC adaptation of Nicholas Nickleby).

Having moved seamlessly from pubs with Caine, to submarines with Harrison Ford and Liam Neeson (in K19, out this summer) and rainforests with Olympia Dukakis (The Intended, also out this summer) the busy Mr Feild is about to start filming the lead in Peter Greenaway's latest, The Tulse Luper Suitcases, which also features the fabulous and multi-talented Debbie Harry and will doubtless be as odd as it sounds. All of which should nonetheless be considerably more rewarding than a previous role on American television as Jack in the memorably named Jack and the Beanstalk: The Real Story.
