1. An apparatus comprising a computer processor for animating a moving and speaking enhanced-believability character in real time, comprising: i. a plurality of behavior generators each responsible for a respective aspect of facial behavior, at least some of said generators being configured with a respective time definer defining time intervals and generating behavior elements in accordance with said defined time intervals; ii. a unifying scripter, associated with said behavior generators, said unifying scripter operable to combine said generated elements into a unified animation script for said enhanced believability character; and iii. a renderer, associated with said unifying scripter, said renderer operable to render said enhanced believability character in accordance with said unified animation script, iv. an executor, associated with said renderer, operable to execute animating of said rendered enhanced believability character, wherein said behavior generators are configured to continue to generate behavior elements during execution of said animating of said rendered enhanced believability character in accordance with said defined time intervals and said renderer continues to render the enhanced believability character in accordance with respective ones of said generated behavior elements as said behavior elements are added to said unified animation script during said execution of the animating of the rendered enhanced believability character, said unifying scripter randomly selecting elements from different ones of said behavior generators in response to stimuli for addition to said unified animation script.
