Here's another one I remember hearing about:
Do you remember the original "Perry Mason" TV show that ran from 1957 to 1966?
One of the regular actors on the series was William Talman, who played the role of the District Attorney "Hamilton Burger."
Well, in 1960, the police raided a "wild" party at Richard Reibold's Hollywood home where the people were not only enjoying some pot, but they were also naked! One of the people arrested at this shindig was William Talman!
This was quite the scandal, and it led to CBS invoking the "morals clause" in Talman's contract and firing him from "Perry Mason." The charges were eventually dropped, but the trial was all over the newspapers and especially the tabloids. (Talman always maintained his innocence, and following the trial the judge in the case criticized the police for arresting him.) CBS was deluged with fan mail demanding his return, and they reinstated him later that year.
(An aside about Talman: He was a heavy smoker most of his life, and he was diagnosed with lung cancer in 1967. You may remember seeing him in an anti-smoking television spot in 1968 and 1969. He was enraged that actors were afraid of losing opportunities to make lucrative cigarette commercials (a staple of TV ads in those days) by making anti-smoking messages, so he did something unheard of and very courageous at the time -- he volunteered to make a short film for the American Cancer Society, part of which became the TV spot. He was the first actor to do such a thing. When the film was made, Talman knew he was dying and in excruciating pain.
"Before I die I want to do what I can to leave a world free of cancer for my six children.")
