This year marks the 50th anniversary of George Balanchine's Jewels, and companies around the world are paying homage. While last summer's Lincoln Center Festival collaboration with New York City Ballet, Paris Opéra Ballet and Bolshoi Ballet was all glamour and excitement, Pacific Northwest Ballet is taking a reverential look back in advance of its opening performances next week.

In 2014, PNB artistic director Peter Boal invited four stars of Balanchine's original 1967 cast—Violette Verdy, Mimi Paul, Edward Villella and Jacques d'Amboise—to coach the company in their signature roles. And, thank heavens, they captured it all on film. This 20-minute promotional documentary offers priceless footage of them in rehearsals, interviews and lecture demonstrations, offering fascinating insights into Balanchine's creative process and original intentions.
