Who you gonna Zoom? The cast ofGhostbusters! That's what Josh Gad did this week on his latest virtual reunion video for charity. Bill Murray, Dan Aykroyd, Sigourney Weaver, Ernie Hudson, Annie Potts, and director Ivan Reitman also joined the Zoom call--as did Reitman's son, Jason Reitman, who's helming the upcoming Ghostbusters: Afterlifereboot. Consequence of Sound notes that the cast paid tribute to the late Harold Ramis during the chat, while singer Ray Parker Jr. closed out the half-hour Zoom by performing his hit Ghostbusters theme song. Ghostbusters superfan Kumail Nanjiani even made a surprise appearance to run lines from the film with the cast. The event raised $4,300 for the Equal Justice Initiative, with another $125,000 being donated by Barefoot Wines, which sponsors Gad's Reunited Apart series. Gad has previously spoken to the cast of Back to the Futureand is seemed to tease that the next episode will feature the cast ofFerris Bueller's Day Off.
