Silent-era film scholarship has all too often focused on a handful of German directors, including Fritz Lang, F. W. Murnau and Ernst Lubitsch, but little attention has been paid to arguably one of the most influential filmmakers of the Paul Leni. This collection - the first comprehensive English-language study of Leni's life and career - offers new insights into his national and international films, his bold forays into scenic design and his transition from German to Hollywood filmmaking. The contributors give fresh insights into Leni's most influential films, including Waxworks (1924), The Cat and the Canary (1927) and The Man Who Laughs (1928), and explores such lesser-known productions as The Diary of Dr. Hart (1918), Backstairs (1921) and the Rebus film series (1925-7). Engaging with new historical, analytical, and theoretical perspectives on Leni's work, this book is a groundbreaking exploration of a cinematic pioneer.
