Mercedes' character and Drew Barrymore's character are very similar in their apearances and roles in our opening scene and the film 'Scream'. In this still shot, mercedes is alone in the house using her phone, and in the still shot of Drew, she is also alone in her house using the phone. They both play vunerable young women who are the victim of the 'bad' people in the film. Both characters are used in the same way. They are both the first character to be introduced into the film, yet neither of them are to be in the film for very long. They are used to introduce what the film is about and what happens to the victims. Their costume is slightly different but they are both wearing everyday clothes (jumper).
