The Exploits of the Emden is a 1928 silent Australian film about the Battle of Cocos the World War I naval battle between Australian cruiser HMASSydney and German cruiser SMSEmden. It consists of footage from a 1926 German film, Unsere Emden, with additional sequences shot in Australia by director Ken G. Hall. Only part of the film survives today.
Unsere Emden was made in Germany in 1926. The movie depicted the German sea captain offering to surrender at the end but Australias Captain Glossop refused, leading to the fight.The Australian rights to Unsere Emden were bought by First National Pictures, but when the film arrived in 1927 they were worried about the casting of Germans to play Australians. John Jones, the managing director of First National, assigned his publicity director, Ken G. Hall with the task of shooting additional scenes. At this stage of Halls career, his only experience in handling film came with reediting movies to meet the requirements of Australian censorship. ........
