Hannah - Character Comparison

I have made a comparison bewtween Hannah and Hayden Panettiere from Scream 4. As they both have similar looks, blonde hair and same height. They are both going to be main characters of the film which is another comparison.
Also the two characters are best friends with the strong character who survives. However, the only difference between these two characters is the fact that Hannah's characters disappears half way through whereas Hayden Panettiere's character is shown throughout the film, dealing with ways to stay alive.
