Ghostbusters (2016)
1 character mistake - chronological order
Directed by: Paul Feig
Starring: Chris Hemsworth, Kristen Wiig, Melissa McCarthy, Kate McKinnon, Leslie Jones
Continuity mistake: At the mansion, the tour guide hits the square on the wall twice.
Patty Tolan: [As a ghost leaves on the subway.] I guess he's going to Queens - he's going to be the third scariest thing on that train.
Trivia: The "Demonic Balloons" that attack the Ghostbusters are almost direct re-creations of real Macy's Thanksgiving Day Parade balloons from the 1930's. The filmmakers decided to use the real designs in order to represent the "spirits" of New York's history... and also because they were quite eerie and unsettling.
