The animation is an art of timing. In the pre-production 3D characters float in the animator’s workspace, waiting to come alive. It is the animator who makes this virtual world believable to viewers. Two characters are chasing down in the narrow hallway. The narrative comes from the flow of motion and timing. What makes this animation exciting is the balance between the two main characters. One is large, and the other one is small. Their sizes and weights feel different while they are interacting with each other in the same space.
