“If you can’t find it, design it.” Following that motto led Lella and the late Massimo Vignelli through a design career that spans products, graphics, publications, furniture, and more. Kathy Brew and Roberto Guerra‘s documentary, Design Is One, traces the Vignellis’ legendary achievements—from New York’s subway signage and identity programs for Bloomingdale’s to Heller dinnerware and Venini lamps—alongside personal anecdotes from the likes of Richard Meier, Milton Glaser, Michael Bierut, and Jessica Helfand. Today it arrives on DVD, complete with ten bonus shorts (unseen footage galore!) and a photo gallery. Prefer to stream? Find the film on Netflix and the iTunes movie store.
