Skerritt's family confirmed his death in a statement, saying: "While the world knew Tom through his remarkable acting career, we knew him for his humor, curiosity, wisdom, generosity and the love he brought into our lives. He cared deeply about imagination, creativity, storytelling, service, veterans, the natural world and helping others find and share their own voices."
Skerritt was twice nominated for an Emmy for "Picket Fences," winning outstanding lead actor in a drama series in 1993. He played the kindly sheriff in David E. Kelley's comedy-drama, which ran from 1992 to 1996 and won 14 Emmys and a Golden Globe. He also appeared in "The Turning Point," "Steel Magnolias" and "Contact."
Born into a middle-class Detroit family, Skerritt spent four years in the Air Force and studied filmmaking at UCLA after being inspired by "Citizen Kane." His first film role came in the 1962 Korean War film "War Hunt," which also marked the debuts of Robert Redford, Sydney Pollack and Francis Ford Coppola. Redford later cast him in "A River Runs Through It," and the two became lifelong friends. "There was such a deep connection we made with each other that it matured into a level-headed friendship," Redford told the Seattle Times in 2007. "His values were close to mine, and he kept his integrity."
Skerritt said he was drawn to "Alien" because the lead actor disappears and "the woman becomes the hero. I really like that idea." He described "Picket Fences" as "written by the best writer on television."
He is survived by his third wife, Julie Tokashiki, and five children.
