An official teaser trailer was released on January 16th 2019, the day after the movie was announced. The trailer featured musical cues from Elmer Bernstein's score, as well as the proton pack sound effects from the original films. The trailer shows the severely weathered Ecto-1 in storage as well as some mysterious (possibly ectoplasmic) slime on a fence.
A sequel to the original Ghostbusters movies (Ghostbusters (1984) and Ghostbusters II (1989)).
Director Jason Reitman is the son of Ghostbusters (1984) and Ghostbusters II (1989) director Ivan Reitman.
Developed under the code name 'Rust City'.
Finn Wolfhard did not know he was auditioning for Ghostbusters as the audition sides were purposefully kept to be generic and vague as the movie was being developed under secrecy.
Jason Reitman did appear in Ghostbusters II (1989) as the kid who tells Ray that, according to his dad, the Ghostbusters are "full of crap".
Finn Wolfhard assumed the '80s-set Stranger Things (2016) in which his character, Mike Wheeler, dressed up as a Ghostbuster for Halloween in Stranger Things: Chapter Two: Trick or Treat, Freak (2017) would take him out of the running and thought that Jason Reitman would not look at his tape because he had already done it in Stranger Things (2016), but Wolfhard ended up getting cast to his surprise because Reitman identified with Wolfhard's audition tape.
According to Dan Aykroyd, this film will also rely on practical effects.
If you look closely when the camera is coming forward to the right of the screen (on the trailer) you will notice a fence covered in slime .
Paul Rudd announced via social media that he would be joining the cast while standing in front of Hook and Ladder 8 (Ghostbusters HQ) in New York City.
Due to the controversy and financial failure of the remake Ghostbusters (2016), any further sequels for that movie were abandoned. This prompted Sony to instead make a sequel to the original two films.
Finn Wolfhard is one of the young stars of Stranger Things (2016) and in one episode, his character Mike Wheeler and his friends dress up as Ghostbusters for Halloween.
Jason Reitman has wanted to work with Paul Rudd since Reitman's short film opened for Rudd's movie Wet Hot American Summer (2001) at Sundance in 2001.
The mine featured in the trailer belongs to the Shandor Mining Co. Ivo Shandor was the architect who designed the building that Dana Barrett lived in on Central Park West.
Carrie Coon and Bokeem Woodbine both starred in Fargo, but in different seasons.
