So many words have been printed about Orson Welles that André Bazin’s study “Orson Welles: A Critical View,” which devotes roughly equal space to biography and analysis, makes a somewhat muffled impact today. Bazin was greater as a theorist than as a critic, and by now his main insights have been reiterated and reworked by any number of subsequent writers, although his thoughts on classical vs. baroque style, his emphasis on découpage, and his interpretation of Welles’s camera angles remain fresh and valuable. Which is more than enough to keep the book alive for serious cineastes.
