|Final girl and scream queen in Halloween|
The first signifier links a good academic level, and the fact she is carrying books signifies she is intelligent. Later on in the film, she forgets a chemistry text book and her friends laugh at her, which is a use of binary opposition, as her friends are the scream queens. The clothes she is wearing are also a signifier that she is the final girl. She is covered up, and the clothes are quite old fashioned, dull and un-sexy. Her hair is also brunette, which is a common feature of the final girl to have. As well as this, Laurie does not have a boyfriend and is a virgin, whereas as her scream queen friends all have sex, and end up being killed. When she is hanging out with her friends, they're smoking but she is not, which signifies responsibility.
How Sidney Prescott defines the final girl archetype in Scream (Wes Craven, 1996):
As with Laurie Strode, she has long brunette hair, and her dress sense is old fashioned and fairly childish. The first time we see Sidney her night gown is what we, in modern day, might typically associate with elderly people. She is also doing her homework, which signifies academia. Her bedroom is also quite childish. Because she is a teen, we would expect to see posters of shirtless boys/men, however there are framed pictures with floral decor which is unusual for a teenagers bedroom.
