NBC has produced a documentary in time to air during the Sochi Olympics on Feb. 23. Unlike with the ESPN film, Nancy Kerrigan decided to participate. In the decades following the drama, Nancy has kept a low profile, even after her brother went to jail for his alleged involvement in her father's death. Sportscaster Mary Carillo, who worked with producer Margaret Grossi on NBC's project, said it took years to get Nancy to participate. Nancy said: "I trusted Mary and Margaret to really tell the story with my perspective." We'll have to wait and see what that is when it airs in primetime. Until then, here's a preview.
