Thriller Opening Analysis (Cape Fear)

Above is the opening for the film Cape Fear. The music played in the background straight away sets an extremely eerie atmosphere. The music being played is produced by an orchestra. The volume is gradually increasing( this slowly builds tension as the audience know something is about to happen) until 56 seconds in. Here the volume is at it's greatest and very dramatic, also the tempo increases. The atmosphere completely changes when this takes place, as it is a lot more powerful and electric. However, the music's volume and tempo goes back to how it was at the start at 1.09.
I find it very effective how the mise en scene is mostly just calm flowing water. By having a very simple opening with basically one image (water) i find that this widens the audiences imagination. The water could link to anything, i.e. blood? Also at 0.40 seconds a black eagle flies across the screen slowly. The eagle represents the bad guy as he is searching for his next pray; like an eagle would. Also using a black eagle also works well as it's black is the color of death and helps make the atmosphere spooky and chilling.
