Next he was tapped by Pixar to pen the script for "Toy Story 3".

His most recent work is "Catching Fire", sequel to the blockbuster "Hunger Games".
While there is no way to know for sure, I will safely assume they wouldn't have handed such an important franchise to someone they weren't 100% sure of.
