Bratt left the series at the end of season 9, stating it was an amicable departure and he expected to eventually return for guest appearances. (He ultimately returned for the season 20 episode "Fed".) Detective Curtis was written off as leaving the force in order to take care of his wife, who was suffering from multiple sclerosis, in her final days. He was replaced by Jesse L. Martin as Detective Ed Green, who was conceived of as more of a loose cannon in the mold of Noth's Logan than Bratt's Curtis was. (Briscoe was described as being a recovering alcoholic, as Cragen had been. Green was described as being a recovering compulsive gambler.) In 2000, Steven Hill announced he was leaving the series after season 10. Hill, who was the last remaining member of the original cast, said his departure was mutual with the producers. He was replaced by Dianne Wiest as Interim District Attorney Nora Lewin, and Adam Schiff was written out off-screen as departing to work with Jewish charities and human-rights organizations in Europe.
