we can i dentify the synergy from the very first stages of the trailer there is a instand point of view shots betwee harry and voldermort, the look of the two caracters shows instantly that they are fearful of each other this is shown in the poster aswell as the magazine. the mise en scene of the trailer again relates well to the poster with the dark backgrounds with the rugged clothing and again shown in the poster and magazine. the jump cuts and medium long shots create the tension and provides a sense of fear and battle to the trailer.
We can see easily again the synergy between the poster and the trailer, the dark background with hogwarts surrouinded in darkness makes it look like there is something up and will create tension as it is not its normally percieved as it is in the poster. the way that only voldermort and harry are on the front cover shows that these two is where the conflict lays, the way that they both create a feeling of fear and nervousness helps us know what to expect in the movie.
We can see from my final anaysis there isnt as much synergy between this and the poster and film trailer however there are some relations that can be identifyed, firstly we can see that there is the effect of broken glass, this now resembles things being broken and fighting which is clearly viasable from the poster and the film trailer. Harry being the centre of attention shows that he is the main reason for the distruction and the smaller shards of glass containing his two friends and voldermort in there shows that the enemy is close to all three of them in the distruction.
