The Hunger Games - What Now?

I saw the first 'Hunger Games' about a dozen times and have seen Catching Fire 3 times so far.  I never read the books and quite honestly I have no interest in reading them either.  I can honestly say that when I first saw Catching Fire I definitely didn't see that ending coming.  In my opinion though, it was by far way better than the first Hunger Games.

Anyone who is a fan of The Hunger Games has to be wondering what Lions Gate plans to do with Mockingjay Parts 1 and 2 since the tragic death of Philip Seymour, who played the Head Gamemaker (Plutarch Heavensbee) in Catching Fire.  Like I said, I have never read the books and I don't intend to but I have to believe, after seeing Catching Fire, that his character plays a pivotal role in the remaining 2 sequels.  From everything I have read Part 1 was wrapped up but there were 7 remaining days of filming left for Part 2 and one major, emotional scene left to film.  I guess I have to wait til November 2015 to find out how they plan to work around the issue of his absence. Sigh.
