In addition to being an Oscar-winning actress and the lead of a billion-dollar movie franchise in The Hunger Games, Jennifer Lawrence can now add best-selling singer to her resume. The song “The Hanging Tree” was performed by Lawrence in Mockingjay — Part 1 and later released to radio stations where it debuted at #12 on the Hot 100, and on iTunes where it sold over 1 million copies. This are just some of the facts packed into the latest episode of You Think You Know Movies, which travels to District 13 for The Hunger Games: Mockingjay!

After Catching Fire, the books’ author Suzanne Collins e-mailed director Francis Lawrence and asked if Elizabeth Banks' character Effie Trinket could be written back into the Mockingjay script. The character was largely absent from the final book, but on Collins’ insistence, they essentially replaced the book character Fulvia Cardew with Trinket because they thought fans would want to see the ostentatious Trinket in the drab, colorless world of District 13.
