“Peter Martins: A Dancer.” Kultur. $39.95. The princely Dane of New York City Ballet is shown at the zenith of his dancing powers and at the start of his choreographic career in this 1978 film. Director Jorgen Leth alternates lightweight interview segments with random backstage footage (spiced with glimpses of George Balanchine). More significant: the revealing coaching sessions with teacher Stanley Williams and an engrossing “Afternoon of a Faun” rehearsal with choreographer Jerome Robbins. Besides a duet from Martins’ own “Calcium Light Night,” the major dance sequences include excerpts from Balanchine’s “Chaconne,” “Agon” and “Tchaikovsky Pas de Deux.” Information: (800) 458-5887. ***
