Real-Life Character Counterparts

So obviously Haig=James Randi, Chistou is meant to be a Uri Gellar expy, and Zander=Anton Lavey with some David Koresh thrown in. Jack Delroy is confirmed to have been a Don Lane-Dick Cavett hybrid, but are there other examples less talked about? Presumably Gus is a stand-in for Bert Newton

I'm guessing Cleo James is a direct reference to Miss Cleo? And producer Leo Fiske looks outfitted and styled to resemble famed producer Robert Evans, although I'm less sure if that's not just a coincidence.

June's arc seems like a direct reference to Lawrence Pazder and his book Michelle Remembers - based off his work with a survivor from a Satanic cult - with even the Conversations with the Devil book cover resembling that of Pazder's book. There's also Kee MacFarlane as a possibility (famed for her work in the McMartin school saga for interviewing kids claiming to have been groomed by teachers in Satanic rituals - and who also was involved in an elicit affair with the main reporter Wayne Satz who broke the story; not unlike what appears to be the case between June and Jack behind the scenes)

The opening documentary also features what looks like an Orson Welles expy for a guest? And the wildlife expert is pretty clearly a gender swapped version of Jim Fowler, a regular on Late Night and Dick Cavett

Any others come to mind?
