This 7-minute black-and-white short film is theatrical with Wreck-It Ralph, and it is a combination of hand-drawn animation and computer animation. I really liked this technique. In this short film, a man tries to send a paper airplane to his love. The director of the short is John Kahrs and the producer is John Lasseter (director of Toy Story, A Bug’s Life, Toy Story 2, Cars and Cars 2).The technique they used that blends hand-drawn animation and computer animation, called “final line advection”, gives the artists and animators a lot more influence and control over the final product as everything is done within the same department; the artists quoted, “In Paperman, we didn’t have a cloth department and we didn’t have a hair department. Here, folds in the fabric, hair silhouettes and the like come from of the commited design decision-making that comes with the 2D drawn process. Our animators can change things, actually erase away the CG underlayer if they want, and change the profile of the arm. And they can design all the fabric in that Milt Kahl kind-of way, if they want to.”
Also, here are some videos from the short.
