Book excerpt: Are you an art-movie buff or a blockbuster enthusiast? Can you reel off a list of New Wave masterpieces, or are you more interested in classic Westerns? Most of us love the movies in one form or another, but very few of us have the all-round knowledge we'd like. 30-Second Cinema offers an immersion course, served up in neat, entertaining shorts. These 50 topics deal with cinema's beginnings, with its growth as an industry, with key stars and producers, with global movements--from German Expressionism to New Hollywood--and with the movies as a business. By the time you've worked your way through, you'll be able to identify the work of George Melies, define auteur theory or mumblecore in a couple of pithy phrases, and you'll have broadened your knowledge of global cinema to embrace not only Bollywood but Nollywood, too. All in the time it takes to watch a couple of trailers.
