Entertainment Tonight has posted the full behind-the-scenes sneak peek from their DVD/Blu-ray announcement last night. It features interviews with Josh Hutcherson, Jennifer Lawrence, and Jon Kilik. In separate interviews, Josh and Jennifer talk about how they both goof off a lot and have a hard time not laughing at each other when the cameras start rolling. Kilik, on the other hand, said that even with their fooling around, they do get right into it once the camera starts rolling.
