The document discusses conventions that could be used, developed, or challenged in a film opening sequence to portray a girl who feels isolated and sad. Isolation would be used to show the girl feeling alone by having her isolated from others. Sadness could be developed with a close-up shot of her face crying to show the emotion. A sense of tragedy could be built by showing her trying to jump off a bridge but being saved by friends. Examples are given from other films to illustrate these conventions.
