The actor's agent Hillard Elkins says Culp died after collapsing Wednesday on a sidewalk outside his Hollywood home. Los Angeles police say he hit his head while on a walk and was pronounced dead after arriving at a hospital.
A preliminary investigation found that his death is accidental.
"I Spy," which aired from 1965 to 1968, was a television milestone. Its combination of humor and adventure broke new ground, and it was the first integrated television show to feature a black actor in a starring role.
