On the occasion of his Researchers' Tales Talk at the BFI National Library, renowned writer and academic Charles Barr talks about the legend of British Cinema Alfred Hitchcock. Barr describes how Hitchcock educated himself in the technical, structural and aesthetic aspects of cinema, and how this helped to form a distinctive narrative in his earlier silent films. He goes on to talk about how he developed his own editing style, constantly learning from his collaborators. Hitchcock was extremely systematic, and was fascinated by the mathematics of editing to create his iconically suspenseful thrillers, and Barr indicates that this fascination began early on in his career. Barr suggests that Hitchock has indirectly, if not directly, influenced almost all film directors and notes that director Paul Greengrass parallels Hitchock in his absorption of nouns, verbs and adjectives of the cinematic language.
