Mark Salling's role in the movie

Sorry I'm just now getting back to this. Mark plays the character of James Rhodes who is the son of Grace (Naomi Watts) in the movie. He along with the rest of the town's kiddies gets sucked into the world of Josiah and he along with every other kid starts developing crazy symptoms such as losing his teeth and getting a high fever. He's part as far as I recall isn't that big in the film. He's kind of an angsty little boy in the movie and doesn't have that many lines.

Hope that helps you. :)

I need more parts.

He also collects serial killer trading cards as a hobby. They have pictures and facts about people such as Charles Manson.
