Anderson (seen above on the left, with Lee Majors on the right) made a career out of playing stern authority figures, from the head of a secret government ops agency on the aforementioned shows to a lieutenant on "Perry Mason."
He got his start in Stanley Kubrick's 1957 World War I drama "Paths of Glory" as a prosecutor and went on to play a colonel in "Seven Days in May" (1964), Joanne Woodward's love interest in "The Long, Hot Summer" (1958), and the titular character's best pal in the TV show "Zorro."
Anderson's many credits include "The Untouchables," "I Spy," "The Fugitive," "Columbo," "The Love Boat," and "Dynasty." His final film role was in 2015's "The Blood Trail."
Anderson is survived by three daughters.
