[1] Gillies landed her first movie role when Whit Stillman cast her as Cynthia McLean in his pioneering independent film, Metropolitan (1990).

Prior to her role as Kathy Stabler on SVU, which she played from 1999 to 2011, Gillies appeared in "Bad Girl," an episode of the original Law & Order series, playing Monica Johnson, a young woman who murders an undercover police officer and then undergoes a religious conversion during her trial and is born again.
The New York Times Book Review said of it, “For Gillies, coziness is a state of mind, the environments we create in our homes to feel at ease.
Think of her as a companion to Marie Kondo, filling up all those spaces once they’ve been decluttered.” She was married to DeSales Harrison, an English professor at Oberlin College, from 1999 to 2005.
