This excerpt is from a documentary chronicling the rise of one of the greatest landscape painters of all time, Joseph Mallord William Turner (1775-1851), who rendered the subtle effects of light and atmosphere in revolutionary ways. A barber's son, he entered the Royal Academy art school at age fourteen and became, over the course of six decades, the leading British artist of his era. This overview of Turner's career and influences includes footage of locations important to him in Wales, Switzerland, and England, and readings from writers and artists of the era, including John Ruskin and Lord Byron. A 30-minute version of the film may be purchased at the National Gallery of Art. Narrated by Jeremy Irons and produced by the Gallery in conjunction with the exhibition J.M.W. Turner, the film is made possible by the HRH Foundation.
