Green Days: Dinosaur and I

Green Days: Dinosaur and I is a 2011 South Korean animated film. Without the high-tech computer graphics and three-dimensional techniques that dominate the animation industry, the film was hand-drawn in pencil, with 14 animators using 100,000-plus sheets over a period of 11 years. It premiered at the 15th Busan International Film Festival in 2010 and competed for the top prize at the 2011 Annecy International Animated Film Festival.
