The present paper investigates how different ideas that have been proposed might be combined to identify subsets of similarly constructed films (i.e. exhibiting comparable cutting structures) within a larger body. The ideas explored are illustrated using a sample of 62 D.W Griffith Biograph one-reelers from the years 1909–1913. Yuri Tsivian has suggested that ‘all films are different as far as their SL struc- tures; yet some are less different than others’. Barry Salt, with specific reference to the question of whether or not Griffith’s Biographs ‘have the same large scale variations in their shot lengths along the length of the film’ says the ‘answer to this is quite clearly, no’. This judgment is based on smooths of the data using seventh degree trendlines and the observation that these ‘are nearly all quite different one from another, and too varied to allow any grouping that could be matched against, say, genre’1. While the basis for Salt’s view is clear Tsivian’s apparently oppos- ing position that some films are ‘less different than others’ seems to me to be a reasonably incontestable sentiment. It depends on how much you are prepared to simplify structure by smoothing in order to effect comparisons.
