They’re taking a trip to Star’s Hollow.  In the upcoming documentary “Drink Coffee, Talk Fast,” directors Meghna Balakumar and Kevin Konrad Hanna revealed that it wasn’t hard to get the show’s stars to talk.  “Everyone’s been really, really open to the point where it’s actually been surprising,” Balakumar exclusively told The Post.  “We went to people’s houses [to interview them]. We actually spent the day with them and their families, and kind of got to live their lives for a little while.”
