Looking closer into Harry Potter and the Deathly Hallows P1 poster- 

The first thing we notice when looking at this poster is what is happening in the picture.

The three characters are running, this suggests the genre of the film and that it has a lot of high energy in it. It also helps to add a bit of intrigue, audiences my wonder why are the characters running, are they running away from something, to somewhere...? 

The picture shows the three main characters. It shows a little more emphasis on Harry, being the main character, he is the largest of the three and at the front. 

There is use of a tagline just under the main title. This tagline is short and snappy, allowing audiences to remember it, also it adds more intrigue into what the film is going to be about. 

The title is the largest text on the poster, it's clear and easy to read. It catches the audiences eyes, you cant look at the poster without noticing it. 

The release date uses the word "epic", this is positive and persuasive language showing how important the film is.
