FLASHBACK : A narrative device used in Film (as in literature) to go back in time to an earlier moment in a character’s life and/or history, and to narrate that moment. Flashbacks, then, are most clearly marked as subjective moments within that narrative. Flashbacks are a cinematic representation of memory and of history and, ultimately, of subjective truth. (Hayward, 1996)
The flashback is a privileged moment in unfolding that juxtaposes different moments of temporal reference. A juncture is wrought between present and past and two concepts are implied in this juncture: memory and history. (Turim, 2013)
