NUTS ABOUT IT: Every year for 26 years, since she played a children's part at age 10, Molly Lynch has been involved with a production of "Nutcracker." She's Ballet Pacifica's artistic director for the 100-year-old ballet, which opens at the Laguna Playhouse Dec. 17. . . . "To me, it's not Christmas without the 'Nutcracker,' " she says. And of course, she'll be in the audience when the Kirov Ballet's "Nutcracker," above, opens tonight at the Orange County Performing Arts Center.
