Don Johnson also appeared on another QM production, The Streets of San Francisco, during the same week in December 1976.
Featuring a true smorgasbord of '70s recurring "B" guest stars (besides A-lister Don Johnson) : alumni for arguably the most famous Charlie's Angels episodes: Christina Hart of Angels in Chains (as well as Manson-like cult devotee in Can Ellen Be Saved? (1974)), and Bruce Watson aka "Margot", the cross-dressing killer in the infamous, Angel on the Line (1981). As for Gary Sandy, he is perhaps most famous for playing the mentally deranged killer who spends his time staring at a lit lightbulb from his bed, then assaults Hutch's girlfriend in Vendetta (1976)
