Two of Britain's leading film directors - John Schlesinger and Gerald Thomas - share the anxiety, hopes and risks experienced by those involved with the movie industry. The Big Screen follows the production of four British films: the eighth James Bond film Live and Let Die, The Optimists of Nine Elms, science fiction-thriller The Final Programme and The 14. Actors Peter Sellers, David Hemmings, Jon Finch, Roger Moore and Jenny Runacre are among those seen at work.
