The document discusses techniques used in a film to depict flashbacks and the psychological effects of war on a character. Scenes set in the present used the same location as flashbacks for continuity. Flashbacks were shown through sepia-toned or black and white footage to indicate they were in the past. Overlapping and layered videos during intense scenes added to the character's stress and sense that the past and present were colliding. Camera angles and music were chosen to help viewers experience events from the character's perspective and see how the war constantly remained on his mind.
