Answer: Campbell Scott
Scott, born in 1961 in New York City, landed the part of Ethan Thomas. Ethan was a prosecuting attorney who filed charges against Father Moore. He first met the defense attorney, Erin Bruner, at a bar and told her he would argue that Moore get the death penalty. Erin asked him why he, as a Catholic, wanted to send a man to Death Row, and Ethan said he represented the people. He argued that what Emily Rose suffered from was psychosis and epilepsy, not possession, and that it was through Father Moore's negligence that she died. In the end, Ethan technically won the case when the jury came back with a guilty verdict, but he lost when the jury recommended Moore's punishment be time served, and the judge agreed to that disciplinary action. Scott guest starred on the TV series, "Independent Lens", "L.A. Law", and "Family Ties."
