Quinn Martin

apologies if already noted

but IV has many references to the TV producer Quinn Martin--noted
references to shows he produced but also directly with Bigfoot's TV
appearances, e.g.:  A Mickey Wolfmann concept--QM's shows were noted
for that voiceover spiel:  A Quinn Martin production

The eponymously-named QM Productions produced a string of hit
television series during the 1960s and 1970s, including The Fugitive,
Twelve O'Clock High, The F.B.I., The Invaders, The Streets of San
Francisco, Cannon, and Barnaby Jones. His series were known for their
highly stylized format: a prologue featuring a stern-voice narrator to
establish the premise and introduce the cast for that episode;
explicitly announced Acts I, II, III, and IV; and an epilogue, again
featuring the narrator.

grew up on all this shit so it resonates

p.s. fwiw...QM's only movie is called The Mephisto Waltz
1971--starring Curt Jurgens and Alan Alda (!)-that's some pairing--a
small but effective little horror flick about soul switching
