The Hunger Games: Mockingjay book to film differences

The following are noted differences between the original Mockingjay book and The Hunger Games: Mockingjay - Part 1 and The Hunger Games: Mockingjay - Part 2 films. As the novel's author Suzanne Collins was also one of the screenwriters as well as one of the film's producers, it should be inferred that all changes were approved by her. This page contains spoilers from both.

Please note: Try to organize changes by section and present them in close to chronological order.
