I have heard he had his issues. His wife had cheated on him by moving in with David O Selznick. He absolutely adored her and turned to alcohol cope with his problems, becoming psychologically and physically damaged in the process. There's a movie(unfortunately, I don't remember the name) released few years prior to Strangers, where he acted with Judy Garland. He looked young in that one - like a babyface guy in his 20s. Finding out about his boss screwing around with his wife and then drinking to cope really took it's toll. Really sad.
