Earlier in the month the Reitmans along with cast members from Ghostbusters: Afterlife were at New York Comic Con. At the big (apple) east coast con, there was a Ghostbusters: Afterlife panel.
For ghostheads and others that could be there, they were front row (or close enough) for the panel and a screening of Ghostbusters: Afterlife! In US theaters on November 19, 2021.
Sony shared this nearly 30 min Ghostbusters panel at their Ghostbusters YouTube channel. I haven’t watched it yet, not sure when I will. Hopefully the NYCC panel will be included on a future Ghostbusters: Afterlife home video release.
