Book excerpt: Other Canadian film producers concentrated their efforts on short productions, mostly in government or commercial companies such as Associated Screen News of Montreal. The works of Gordon Spalding, Bill Oliver, and Albert Tessier are discussed in this context. Morris concludes with the founding of the National Film Board which, under the dynamic guidance of John Grierson, was to breathe new life into a moribund industry. In a postscript Morris explores some of the reasons for the unique development of Canadian film making -- particularly its use of natural settings and documentary when virtually the rest of the world's industry was following the Hollywood pattern of studio location and fictional plots -- and examines the relationship of the early industry to later developments in Canadian film making. At a time when Canada's cultural industries are struggling to survive in the wake of the Free Trade Agreement with the United States and under the threat of Free Trade with Mexico, Embattled Shadows makes essential reading.
