Need a great excuse to get away from the family on Thanksgiving? Go see the new Ghostbusters movie!
This is technically the sequel to number 2, and is set many many years later, and picks up with Egon's grandson, discovering the Ghostbusters legacy in their family.
Even with all the cool effects, my favorite part of this trailer is at 2 minutes, when you hear the old quirky sound of the car, Ecto-1.
