The flag of the United States of America appears in the 3rd movie to follow the Ghostbusters franchise.  This is not a reboot, not a remake, nor a remutartation - like Malefecent. 

A reboot is based on the original with the same beats and same characters, keeping the characters intact.  A remake is a new adaption, with slight changes.  A remutartation is a new story mixed with alien elements and breaks significantly with the original tone and or story line.

Ghostbusters - The Video Game is a sequel in the sense that it follows the storyline, because the characters from the Ghostbusters movies further a new original story, often referencing their experiences from the first two movies.  It is a virtual Ghostbusters 3 film, set in the year 1991.

Although this media-game is not an official Hollywood movie, it was created in 2009.  It builds on the storyline of Ghostbusters 1984.  Most importantly it stars the original cast who voice their own digitized avatars: Bill Murray as Dr. Peter Venkman, Dan Akyroyd as Dr. Raymond Stanz, Harold Ramis as Egon Spengler, and Ernie Hudson as Winston Zeddemore.   Like the first Ghostbusters movie, Dan Akyroyd and Harold Ramis were responsible for writing the plot of this immersive media-video-movie game.

Another classic note of this Ghostbusters project is the producer of the media-game by the ultimate Early 80s home videogame console - Atari.  This Ghostbusters package is a gift for true blue fans, faithful to the tone and style of the first Ghostbusters movie.

Of vexillological note, during the rematch of the Stay Puft Marshmallow Man,  A 50 starred US flag can be seen flying along the side of building.
