Book excerpt: Many British films never make it to the screen. Obstacles of finance, censorship, distribution or creative breakdown can appear in their way, and they might even fail to get beyond the script stage. This book collects new essays by leading scholars that use archival resources to reconstruct the stories behind a range of films by prominent film-makers. These thwarted productions are all too often excluded from histories of British cinema, but the accounts of their unmaking contained in Sights Unseen provides an illuminating insight into the factors which have served to undermine the stability of the film industry in Britain.
