Nash's prolific career as a director of fiction films, often from works by popular authors of the day, such as
Hall Caine and
W.P. Drury, was ended by the official condemnation of his 1921 film
How Kitchener Was Betrayed. The film suggested that the vessel carrying
Lord Kitchener had been sunk by enemy action rather than a mine, leading to a de facto ban on the film in Britain. After this setback, Nash worked on a number of documentary films for the
Federation of British Industries on topics including the
Manchester Ship Canal,
Oxford University Press and the British underwear industry. His wide experience on films with naval subjects saw him work as an advisor on
Walter Summers' 1927 film
The Battles of Coronel and Falkland Islands. Up until 2007, the scarcity of information on Nash and his work has meant film historians have neglected his contributions to the development of British cinema. ==Selected filmography==
