Old Hollywood as expertise
Spellbound Tell-All is Z's fictional Old Hollywood podcast in Jumbo Dumbsludge / NEVER FORGET. The source sketches its field as glamour and decay, rises and falls, film ranches, executives, costumes, sexual politics and the minor machinery around studio history.
Z's expertise matters more than the brand itself. If a general reader has never heard of King Baggot, that proves little. When somebody who makes rent by remembering Old Hollywood has never heard of him, the omission becomes narratively radioactive.
A companion medium
Spellbound Tell-All is the cinema-history counterpart to X and Y's Ringside Retro Wrestling Wrap-Up. Both turn obsolete entertainment into current media; both monetize acts of remembering; both are defeated by the archive they claim to know.
