JLaw spilled about her final scene as Katniss during the Mockingjay Part 2 press panel, and it turns out that she had two very important people beside her during her last moments as Katniss. (Psst: Spoilers ahead for those who skipped the books!)
Yep, Katniss has kids at the end of the movie - and they just so happen to be her relatives IRL! It completely kicks up the cuteness of that final scene, even if we'll still need plenty of tissues to get through the new movie. Someone start writing a Hunger Games spinoff franchise ASAP - I'm not sure my fangirl heart can live without it.
I feel like I had two final endings with Katniss, the one where we wrapped the film in Berlin with everybody, Woody [Harrelson], Josh [Hutcherson], and Liam [Hemsworth], and everyone that was there... [T]hen I had a last scene about a year later. with my nephews, which was so special... they played my children in a scene we shot. So it was like this amazing closure to this character that I had loved for so many years, to have my blood family there [in addition to my Hunger Games] family.
