It is fairly well know that cinematic digital effects are most often rendered on *nix machines with efficient numeric code. http://www.linuxjournal.com/article/9951
But Python sometimes has a role too: from the middile of the above link ''' Tippett Studio: Linux Python Pipeline JET is a proprietary Python-based system comprising software tools and scripts used to implement a visual effects and animation pipeline. A visual effects and animation pipeline is an assembly line of software used to organize, automate and facilitate the creation of computer-generated imagery, says Darling. The JET tool is highly customizable, featuring XML-based user-interface templates that can be modified to suit specific types of artists or production needs. JET uses modular template chunks to perform each of the tasks in the pipeline, such as rendering or compositing. The templates are implemented as Python objects and are centrally located. JET is not only implemented entirely in Python, but it's also used to generate Python scripts automatically. These custom scripts form unique pipelines for each computer graphics job to run on the renderfarm. '''
