The opening sequence of 'The Dark Knight', starts off with a establishing shot of the city, form a far distance in the scene, I could denote a mysterious figure standing on top of a tall building, this signifies to the spectators that he/she may be a important character and possibly a protagonist, however the characters identity was not revealed, which creates a sense of enigma, this conforms to a conventional thriller film because a typical thriller film is always restricted in order to create tension through enigma codes. It is important that a opening sequence should always creates tension or suspense so that the spectator are engaged in watching the film, for example in "The Dark Knight", not revealing the mysterious figure makes the spectators curious and wanting to know more and make judgement on the character. The idea that the character is shaded in low key lighting signifies that he/she is dark and evil, which conforms to the conventions of a typical antagonist.
The opening sequence in this film is not structured in linear narrative and it often jumps to different scenes from the film and introduces the characters. The purpose of this non-linear narrative, was to not reveal what the story is about, which creates a sense of enigma, this helps to build tension. However, when introducing the characters from the film, it immediately reveals the characters identity, which doesn't keep the conventions of the enigma codes in the film.
I think this trailer is not a ver good example of a opening sequence for a thriller film because ther is no tension building, which doesn't capture the spectators attension. The reasons why it doesn't build up any tensions was because it doesn't have any soundtrack playing. It doesn't have a sense of normality because it went straight into the action, for example the car chase/race. This would bore the spectators because the spectators doesn't know what is going on and is not getting involved. However, I think that it creates a sense of enigma because it doesn't reveal much to the spectators,which is a conventions of a thriller film.
