Chase wrote several episodes of "Tales of Wells Fargo" (1959), "Overland Trail" (1960), "The Detectives" (1961), "The Tall Man" (1961), "Whispering Smith" (1961), "Bonanza" (1962), "Route 66" (1962) and "The Roy Rogers and Dale Evans Show" (1962). He did some uncredited writing on "Mutiny on the Bounty" (1962) and wrote "Gunfighters of Casa Grande" (1964). Chase continued working for TV shows such as "Daniel Boone", "The Virginian" (1964), and "Branded" (1965). Chase's final credits include "A Man Called Gannon" (1968) (a remake of Man Without a Star) and "Backtrack!" (1969) (a theatrical release of his 1965 The Virginian episode "We've Lost a Train", which was the backdoor pilot for the 1965–67 series Laredo).

The critic elaborated:The Chase Western story is presented in a physical progression across a larger-than-life landscape, an epic journey west which allows forces of good and evil to interact...
