I am not entirely sure if this is true. I am a Finnick fan, i do Liebe him a lot but I don't want him to not die in the movies, because it will just add Mehr things to the Liste of changes they are making to the movies. I wan it to be as close to the Bücher as possible.
I didn't enjoy the fact that he had died in the Bücher but I always believe that Filme that are based on Bücher should be exactly like them. It shouldn't be changed, cause it's not just his death, there would have to be Mehr script for the character, it would just be complicated.
