Day & Night is a Pixar animated short film, directed by Teddy Newton and produced by Kevin Reher. It was packaged to be shown in theaters before Toy Story 3, and has been released to purchase on iTunes in the United States.
Unlike most other Pixar shorts, the animation style combines 2D and 3D elements, and Up production designer Don Shank says it is "unlike anything Pixar has produced before".Synopsis
Day & Night follows two anthropomorphic characters, Day and Night. Inside Day is a day scene with a sun in the center, and inside Night is a night scene with a moon in the center. Whatever goes on inside of Day or Night expresses normal events that typically occur within a day or night, respectively, and these events often correspond with actions or emotions that the characters Day or Night express. For example, when Day is happy he will have a rainbow inside him, and when Night is happy he will have fireworks inside him.
