Conclusion of flashback

Film I have watched: American Beauty, Walkabout, The diving bell and the butterfly, Sherlock Holmes, Scott Pilgrim, Memento, Sherlock Holmes(film), Pulp fiction, Across the Hall, Citizen Kane, God and monsters,.... (still watching).

From these films I have get a conclusion about flashback below.

Some flashbacks are used at the end of the films, to the narrative, it gives a briefly conclusion of the main character's life ,memories and etc. Like the film American Beauty (1999), when the dad was killed by his neighbour, the film begin to flashback, totally flashbacked for 3 times, introduced the reflection of the main character's wife, daughter and daughter's friend who have heard the sound of gunshot. When introduced one person, the film flashbacked the life of this person with the main character in early days. In the meanwhile, voice-over is used during the flashback, the main character memorizing his life and making conclusion in his words. The film Walkabout (1971), the end of the film is the only flashback of the film, when the little boy threw stones, the flim begin to flashback to the life of a city, so as to compare the original life and the city life. To the plot of the film, voice-over is used for the main character to memorize and conclude the period time of adventure, it's a way of giving a conclusion of the film. Maybe this voice is from the little boy who had been grown up.

Another kind of flashback is used in the middle of the film, which gives the important backstories to audiences before introducing the event which will be happened to the main character next. And the flashback pushes the development of the plot. In the film The diving bell and the butterfly (2007), the author uses flashback to remember the main character's normal life before he got the illness and disabled. In the film Gods and monster (1998), flashbacks were used to memorize the scene that the main character (the hollywood director) was directing films, fighting in the war with his army. The flashback gives audiences the background information that the main character got an illness that a person always remember the things happened before.

This kind of flashback is used for remembering what happened by following a main story line, so as to solving the confusion and working out the suspense. To the plot, these flashbacks are used to show what had happened to the main character, like Memento, Across the hall and Pulp fiction.
