Book excerpt: This collection of essays by Rudolph Arnheim (film criticism, U. of Michigan) explores film theory, criticism, and many classic films from the silent and early sound period (the 1920s and early 1930s). The majority of essays included in this collection were written and published in Berlin during the Weimar Republic, and have been translated into English for the first time. Arnheim argues that up until 1930, film artists created pure forms of cinema crafted with a narrative economy which could unify the most varied of effects. As movies became more realistic looking due to technical advances, cinema began to lose its integrity and viability. Paper edition (unseen), $18.95.
