With this episode, the opening of the series changed significantly. For the first five seasons, the show began with a teaser that cut to the opening titles at a dramatic moment. Henceforth, the series opened with an animated silhouette of Mannix running toward the camera which then cut to the opening titles. A shot of Mannix skiing from season five's "Cold Trail" is also added. The music is also changed somewhat, using a jazzier version of Lalo Schifrin's theme.
The kid actor, Jimmy Putman, died at age 33, in 1995. He was crushed by a tractor. This was an apparent suicide.

Bruce Watson is the second actor in this title to have committed suicide. He died at 68, it is unclear how.
