Yeah! I've already watched the movie. And it gave me more insight in writing The Spark of the Uprising. Scenes from Catching Fire movie/book will only be in the first 7 chapters. After that I have to read Mockingjay again to recreate some scenes like the sewage and the mutt traps and stuffs. It's like almost 2 years since I read mockingjay so I already forgot some of the scenes.
Thanks @TaygenLockyer! I am writing chapter 4 right now. Having a hard time because I have to read Catching Fire and make some of the scenes as similar as possible. But hopefully I will be able to get into the exciting parts soon... XD
