Harry Potter and the Half Blood Prince

Here the colours used are green and black which symbolise danger, betrayal and death -all of which we see in this film. Also the fact that the castle itself is black shows that enemies have made it into Hogwarts, possibly even the Half Blood Prince?
The alarming fact that Dumbledore is stood alongside the 'golden trio' tells us that it has gotten really serious and that the evil is going to come face to face with them; that is why they need Dumbledore's help in this movie. Moreover it could tell us that the enemy is a long time enemy to Dumbledore, someone who he knows very well and that is why he is getting involved.
Also the fact that every single character has their wand out in this poster tells us that there will be a full on battle in this movie and that they will be tested in their wand abilities.
Overall i don't think this poster is that successful because it is not as intriguing as the previous posters; therefore i think it relies on the huge fan base for the series to already know about the movie and word of mouth.
