One of the best ways to get inspiration and also motivation is by watching a movie set around the production of a movie.
There are quite a few good ones such as "Day for Night" by Francois Truffaut and "Living in Oblivion" but by far the best and most accurate depiction of the filmmaking process (in our opinion) is "Dangerous Game" by Abel Ferrara. If you haven't seen it you should certainly check it out as it gives the most honest and true vision of the making a live action film.
Are there any films out there relating to the making of a 3D animated film?
