Film research again

http://www.youtube.com/watch?v=16y8C86N9TA In this opening to The Wrong Turn and im looking mainly at the flash backs in this opening. You can tell they are flash backs because they are clearly different from the 'real time' shots. They are edited to blck and white and are split up with titles which add to susspence as it speads the shots out. It also has some close ups of other medias linked to the story (newpaper headlines) which help expxlin whats going on more. We have decided to use flash backs in our film and using this film know we need to do something to them to make them different to 'real time' e.g. black and white.
