Your writing assignment: take a story with a pre-established foundation and craft the next part. Easy, right? After all, you already have a developed world and an ensemble of characters—how hard can it be?! Take another guess.

The screenwriters behind Rise of the Planet of the Apes, 22 Jump Street, and The Hunger Games: Mockingjay – Parts 1 and 2 will converse about the challenges of life-after-the-originals, as well as the difference between trying your hand at multiple installments versus picking up from where someone else left off.
