The American icon behind the Guggenheim museum, Fallingwater and his own home, Taliesin, Frank Lloyd Wright became the greatest architect of the 20th century - not only because of his magnificent talent but because he was a master showman and self-publicist. The sheer scale of Lloyd Wright's career - over 450 buildings in 70 years - is astonishing in itself but there is much more to his story than the romantic myth his autobiography revealed. This BBC documentary explores Lloyd Wright's visionary works and reveals how his life was beset with periods of devastating critical derision, financial chaos, scandal, and a violent but little-known murder.
