## By H.B. Wallis And J.L. Warner. It Was Shot By Warner Bros. Between May And August 1942.

As an illustrative first example we use the following. A data set was constructed from the 77 successive scenes crossed by attributes - Int[erior], Ext[erior],
Day, Night, Rick, Ilsa, Renault, Strasser, Laszlo, Other (i.e. minor character),
and 29 locations. Many locations were met with just once; and Rick's Caf´e was the location of 36 scenes. In scenes based in Rick's Caf´e we did not distinguish between "Main room", "Office", "Balcony", etc. Because of the plethora of scenes other than Rick's Caf´e we assimilate these to just one, "other than Rick's Caf´e", scene.

In Figure 2, 12 attributes are displayed; 77 scenes are displayed as dots (to avoid over-crowding of labels). Approximately 34% (for factor 1) + 15% (for factor 2) = 49% of all information, expressed as inertia explained, is displayed here.

We can study interrelationships between characters, other attributes, scenes, for instance closeness of Rick's Caf´e with Night and Int (obviously enough).
