Target Audience for Shutter Island

Within the first 10 seconds of the trailer, the audience are introduced to the A-list actor Leonardo Dicaprio, which immediately targets a female audience of around 15-35 as he is very attractive, popular and famous.  After the words, "its a mental hospital" "for the criminally insane" are said, a backing music that is quite solemn begins, creating an unsettling atmosphere, which suggests that it is a mystery/psychological Thriller.  This would relate to a wide audience as it is popular with all ages, both male and female, which contrasts to an action, which would mainly target a male audience.  The Federal Marshals (Leonardo and Mark Ruffalo) would attract both a male and female audience:  they are young and attractive and also can be seen as the 'hero' type that males would aspire to be.  Emily Mortimer, a famous actress is also introduced in the Trailer, which would attract an audience as she is well known.  Furthermore, as she is an English actress unlike the other two stars, this could attract more of an audience as it widens interest (English people are going to want to watch an English actress in a Hollywood film).  The Thriller is also set in 1954, which is suggested in the trailer.  As a result, this will attract an older audience also as they could relate to that time - there are flashbacks of concentration camps, etc.  Therefore, the Thriller can be seen as interesting as well as entertaining to watch as it shows shocking images, which emotionally attach an audience because it relates to real life issues.
