This is a budgeting term that found its way into the regular vernacular of movie crews. Technically it's any fixed cost associated with the production of a film. Below-the-line costs include the salaries of the non-staring cast members and the technical crew, as well as the film studio rental and all associated equipment needed for filming. 

The distinction originates from the early studio days when the budget top-sheet would literally have a line separating the above-the-line and below-the-line costs.

Some of the film crew positions that are considered below-the-line are: Director of Photography, Assistant Director, Dolly grip, Gaffer, Key grip, Best Boy, Art Director, Editor, Composer and Production assistant.

Below-The-Line Tees and Zipper Hoods for men and women are 14.90 and 36. More colors are available.
