What is the ruling on making an Islamic film free of forbidden things, and is it permissible to draw pictures—like those in the link—without music if the former is haram?

The basic principle is the prohibition of drawing complete images of living beings, but it is permissible to produce purposeful cartoon films and images that are not clearly defined or are not in a form that imitates living beings. These are not among the prohibited types of imagery. Music must be avoided in films.
