Dennis Hopper, one of Hollywood's last great cult figures, is best known for his depiction of social outcasts in films such as Rebel Without a Cause and Apocalypse Now, as well as for directing classic films like Easy Rider. Hopper has also, however, made a name for himself as an artist and a photographer. His photographic chronicle of America in the 1960s, a decade marked by awakening and rebellion and documented by Hopper in forceful black-and-white pictures, has now become legendary. A System of Moments, published on the occasion of a major retrospective exhibition at the MAK, Vienna, is a kaleidoscopic documentation of painting, photography, film, and life. It is the first comprehensive publication that takes in to account all of the diverse artistic activities in Hopper's nearly 50-year career, and it examines particularly the subtle connection between genres that is a hallmark of his work. For the first time, recent photographic works, which emerged after a long hiatus from the medium in the 1990s, are also presented. A major retrospective that will be the definitive statement on Hopper's career.
