Catching Fire's roles for Josh Hutcherson and Jennifer Lawrence may call for changes fans won't be happy about. Although fans expected The Hunger Games sequel to have minor changes from the book, some of those changes will seem drastic.
When Jennifer took on the character Katniss, many people were disappointed because in the book, Katniss is clearly not a "white" girl. The character from the book has olive skin and brown eyes. That was one major change many found hard to accept even though Lawrence has done an amazing job with the role.
Nina Jacobson, the producer of the sequel, said, "It's as agonizing for us to lose things from the book as it is for a fan. I want every single thing in there. But you know what? If you have to give up something in order to give more time to Katniss and Gale or to Effie as she starts to feel a conscience, you make the sacrifices in order to serve the characters and themes that are more essential."
The Hunger Games: Catching Fire will bring more departures from the book. Josh's character Peeta will be given the gift of swimming. In the book, "his character was paralyzed with fear when other tributes dive into the water." Hutcherson does his role justice but that's one major change!
Also, Bonnie and Twill from the book will not exist in the movie. They are the ones who tell Katniss about District 13. While the storyline will remain with District 13 intact. Those vital characters will not appear in the movie.
Lastly, District 12's peacekeeper, Darius, won't be added into Catching Fire either so don't expect anyone to intervene while Gale gets whipped.
Fortunately even with some tweaking, Josh Hutcherson and Jennifer Lawrence bring exactly what's needed to their roles. This movie wouldn't be the same without them. They've developed a friendship that goes beyond the set. At least they'll still be in the movie, right?source
