Hackett appeared twice on ABC's "The Rifleman", starring Chuck Connors and Johnny Crawford. In both episodes, "Bloodlines" (1959) and "The Clarence Bibs Story" (1961), his fellow guest star was Denver Pyle. He was cast as Daniel Malakie in "Bloodlines", the father of three boisterous brothers headed to trouble, and then as Clarence Bibs in the episode of that same name. Bibs is a handyman who after cleaning a gun accidentally kills a notorious outlaw, Longden (X Brands). Then, Longden's former partner, George Tanner (Denver Pyle), comes to town but avoids confrontation with Bibs and accepts the explanation that Wicks' death was accidental.
