"The Line" is a term in film direction for the formula of framing the human form in the most visually appealing manner. In standard direction of a portrait shot (closeup of the human face) 'on the line' has the character's eyes framed 2/3rds of the way up from the bottom of the screen. With a full body shot of one or more people, the line is usually drawn through the face(s) of the focal character(s), again 2/3rds of the way up from the bottom of the screen. Framing the face in this way lends an air of symmetry to the shot, as it roughly matches the placing of the eyes in relation to the human head. Examples of this can be seen in almost any mainstream movie.

Framing the human face or form with the eyes 'below the line' is often used by alternative filmmakers as a method of unsettling the viewer as it unbalances the feel of the shot, a good example of which can be seen in David Lynch's 'Eraserhead' where Lynch often moves Henry's face to the centre of the screen in the more intense scenes.
