Ghostbusters Reboot: 29 Easter Eggs, References & In-Jokes
27. You Can Buy The Book
As another part of the viral marketing campaign, you can actually buy the book that kicks off the entire plot - Ghosts From Our Past: Both Literally And Figuratively by Erin Gilbert and Abbey Yates.
It's available on Amazon here in both digital and hard copy (though the price suggests it's probably not the tome it appears in the film.
The book also has profiles for both Yates and Gilbert on Amazon.com, there's a forward by Martin Heiss (even though that makes ZERO sense in the internal logic of the film) and an Epitaph by Chris Hemsworth's idiot Kevin.
The best Easter Egg in the book is in tribute to Ryan Kemp - Ghostbusters superfan and founder of the Western Kentucky Ghostbusters - who sadly passed away in 2015. The book's Spectral Classification system is named in his honour, and included in the book, and there's also a tribute to him in the film's credits too.
