Guest stars David Soul and Robert Urich would co-star again a year later, as vigilante cops against Clint Eastwood's "Dirty Harry" character in "Magnum Force" (1973).
Guest stars Jim Davis and Lou Frizzell would the following year work together again in an episode of Cannon (1971) titled The Seventh Grave (1973).
This was the first new episode to air after J. Edgar Hoover's death four months prior, and this season debut has a slightly different opening sequence. This sequence provided a preview of the episode, then the titles and credits, and then the text stating the crime.
