There is no doubt that the Hollywood matinee idol Errol Flynn (1909 - 1959) was the Charlie Sheen of his day, and thanks to the unrelenting press control that the Hollywood studios exercised over the fan magazines of that day, we probably only know about a quarter of his assorted debaucheries. He was a masher and a lush, and the one law suit that the studio executives couldn't kill was
"the great case against him for statutory rape which, had it stuck, would have given him jail for fifty years. For weeks in 1942 it replaced the war news in the headlines."
In 1938, Flynn wrote an article in which he weakly defended the unique moral codes of Hollywood actors; you can read it here.
