Created by Earle Stanley Gardner, in 1933, Perry Mason appeared in over 80 novels and short stories, becoming one of the best-known fictional characters of all time. Movie adaptions began almost immediately, in 1934. A radio series began in 1943.
The iconic tv series began in 1957, and ran for nine seasons. Years later, tv movies began to air, three or four per year, thirty in all (1985-93).
In the original series, there were five main characters:
Barbara Hale's husband, Bill Williams, was rumored to be gay.
They had one son, William Katt (The Greatest American Hero)
Talman was also rumored to be gay, although he was married three times. He was fired in 1960, after the police raided a party he was attending, and found the guests (both men and women) nude and "high on marijuana." Burr and other cast members intervened, and got him re-hired.
5. Homicide detective Lt. Tragg (Ray Collins). He was probably straight.
