A star of the prison comedy drama, “Orange is the New Black,” said she was the victim of sustained sexual interest from actor Geoffrey Rush, culminating in the Academy Award winner exposing himself to the much younger actress and peering at her while she showered. Yael Stone, an Australian actress who plays inmate Lorna Morello in the Netflix hit, told a television interviewer that she played along with his flirtation and sexual banter during a Sydney theatrical production in 2010 and 2011 because she was terrified of upsetting such a powerful figure of the acting world. Rush, 59 at the time, was a star of the “Pirates of the Caribbean” movies.
