John Forsythe, star of Dynasty and voice of Charlie in Charlie's Angels, died Thursday at the age of 92. The immediate cause of death was pneumonia, but the actor had also suffered from colorectal cancer.

Forsythe is best known for his role as Blake Carrington on the television show Dynasty, which ran from 1981 to 1989. He also provided the voice of Charlie's Angels's Charles "Charlie" Townsend—a character the audience never saw throughout the show's 1976 to 1981 run. His other roles included Bentley Gregg on Bachelor Father and several movie parts.

People magazine rounds up former co-stars' reactions to Forsythe's death, including Joan Collins, who called him the "last of the true gentleman of the acting profession."
