No, just the first movie was the focus of Afterlife while Ghostbusters II was to be referenced more subtle and less in our face. With Ray's Occult being the most in your face and the opposite end, the Giga Meter being a blink and miss cameo. Or if you're a prop fan, you'll see that Peter, Ray, and Winston's Proton Packs reference Ghostbusters II via its ribbon cable.
Was it ignored? No. It was there on the periphery.https://uproxx.com/movies/jason-reitman ... interview/
I wish I could talk to you about [Egon deciding to repaint the Ghostbusters II logo on the Ecto-1.]
I’m just saying that’s a plot that is not in this film and we have ideas moving forward.
Ghostbusters II, definitely canon. There are references to Ghostbusters II in Afterlife. We meet Ray working at Ray’s Occult. The toaster from Ghostbusters II is in the kitchen in the farmhouse. There’s actually lots of lost of Ghostbusters II details but nobody knows Ghostbusters II outside of Vigo the Carpathian and the Ghostbusters II logo. So there’s this assumption that it is not canon but it is definitely canon.
As for Grooberson's line. Who will you believe, a fan or a Ghostbuster? As far as Grooberson knew, there wasn't a ghost sighting in 30 years. Just how closely was he monitoring paranormal activity in NYC for him to make that statement? In the USA? The world? Let's just say "30" is totally accurate, then 1991,activity started to decline and as Ray mentions there were less and less calls a week. So along with that, Ghostbusters were less in the news and less people would go around talking about their ghost encounters. So a false positive in a way, if everyone stops talking about ghosts and there's less press coverage then it seems like there were no ghost sightings.
Did Podcast wear a sensory cap from GB2? I recall he wore the Aura Video-Analyzer colander from GB1 that was used on possessed Louis.
Jason suggests Ecto-1 and 1a are on in the same. And we know that one of the cars turned into Ecto-1 for filming was the Ecto-1a Sony had in storage. And the more eagle eyed fans can tell which scenes have the former 1a car.
