This looks like an amazing project. 

"A hundred years ago a sixteen year old boy secretly enlisted in World War 1 to find his war-serving father. Using a unique blend of CG and hand drawn animation, a team of feature film artists will bring his story to life as an animated short film called “The Sketchbook”. The team promises to transport the audience into the pages of a sketchbook, and tell this story of hope and sacrifice in the trenches of the Great War."

I can not wait to see this.
