Ghostbusters: Afterlife focuses on mom Callie (Carrie Coon) and her two kids ("Stranger Things" star Finn Wolfhard and McKenna Grace) as they discover their connection to the OG Ghostbusters after inheriting property from her father, Egon, in Oklahoma. The trailer includes glimpses of returning stars Dan Aykroyd and Annie Potts -- and appears to tease familiar ghouls like Slimer, Stay Puft, Gozer and Zuul. The movie, costarring Paul Rudd, opens November 11, 2021.
