Born on Valentine's day, 1960, to a Chinese father and an Irish American mother, Meg was raised in British Columbia by her mother and step-father. Meg started taking dancing lessons at age 12. She became a member of the Connecticut Ballet Company, and the Throne Dance Company. After winning a scholarship to a New York dance school, a continuing back injury suddenly worsened, and Meg was forced to give it up. She went to Los Angeles and pursued acting instead, her first film role being a dancer, naturally, in the 1980 film,
Fame. She made her television debut in
Hill Street Blues… More and made a television movie The Trouble With Grandpa. She then landed leading roles in Psycho II and The Big Chill. She married producer Tim Zinnemann while filming that movie, and the couple had two children, Emily and David. After an Oscar-nominated performance in Agnes of God opposite Jane Fonda, Meg became more reclusive, preferring to keep her personal life out of the limelight. She has made several more films, and had a recurring role in the soapy TV drama Winetka Road, but since 1995 has not done any acting of note. She had a third child with actor Colin Firth, a son named William, and was married to Sony executive John Calley from 1995 to 2002.
