The non-digetic sound of the piano suggests a great cheerful atmosphere, you are not drawn to any suspence or sorrow. In contrast If we were to watch an opening of a horror, firstly you will see the dark/shady colours and the creepy backround music, that helps build the scene. However, each peice of musical, sound effect and/or dialogue give away what type of film this is going to be.Mise En Scene;
The lighting throughout the clip 'he loves me, he loves me not' is filled with few bright colours but mainly the exsistence of Red. The colour imagery has a great deal of happyness. we are drawn to many red hearts and everything associated with it.
--> The pace of the clip was quite metural it wasnt fast or slow. As I watched the opening, the pace made it more relaxing for me to watch. There were several Extreme Close Up (ECU) of the roses, that identified it was going to be a romantic thriller.
Overall there was no immediate sign of thriller which was unusual to the audience as they went into this film expecting a thriller or atleast someting to show it. Although,I believe maybe the point of this was to hook us in at first to think its a happy romantic film, but then shock us with a twist into something horrible that happens.
