Similarities and Differences between different Psychological Thrillers

Altogether our group has analysed Paranormal Activity 3, Black Swan, The Ring, What Lies Beneath, Inception and The Blair Witch Project.
 The similarities and differences include-

Differences:
-All the films analysed start differently for example..
    -Black Swan starts with a dream
    -Inception starts with a flashback
    -The Ring begins by setting the scene with an establishing shot
    -Paranormal Activity starts as a home video of someone painting a baby's room
    -What Lies Beneath starts by going through trees

-In The Ring the production company has changed their original logo to fit with the film

-Paranormal Activity has imaginary friends/spirits in the opening

-Inception includes weapons in the opening


 Similarities
-Black Swan and Inception both included synchronous sounds and close ups in the first 2 minutes perhaps to show emotion

-There is a young child featured in Paranormal Activity, Inception and further on in The Ring

-Shows women first in Paranormal Activity, Black Swan and The Blair Witch Project maybe this could be a hint to if the female is the main character

-In all of the openings music is used to build tension

-Another way to create tension is a heavy breathing sound in the background this had been used in Black Swan and What Lies Beneath

-Handheld camera used in Paranormal Activity and The Blair Witch Project maybe because of a small budget and to add more realism.
