Opening sequence- textual analysis of Flightplan

As part of my genre research, I had to textually analyse three opening sequences to help me create a clear idea of what conforms to thriller genres. The analysis of the openings will make me more knowledgeable on what techniques are used in thrillers and how this creates an effect upon the audience. 
This research will help me and my group when creating the pitch for our own thriller opening sequence.

Flightplan
The genre has a solemn tone and creates confusion in the narrative via the use of flashbacks. In addition, a foreign language is used to create even further mystery and confusion in the audience. But, some English was used to intrigue the audience. The dialogue "...trauma to your husbands head at the fall" answered some of the questions produced by the opening scene but it also resulted in even more! It created a feeling of danger, sadness and enigma, captivating the audience. The main character was shown in both past and present time, the portrayal of the two different time scales was shown via the use of media language. Stereotypical representations were used via the portrayal of an innocent woman and vulnerable child due to the collapse of their family unit with the loss of the male protective figure. Also, the representations of the male antagonists dressed in black connotes danger and conforms to convention showing the threat they produce to the bereaved family. The lighting and sound were slightly different in the two situations to show the difference between the two narratives. For example hyper-real sound was used when the raindrops fell from the umbrella, this emphasized what is present and actually happening not a flashback from the past. However, there was only subtle differences, to ensure the audience remained confused and couldn't distinguish the difference in time. Small details such as the time on the clock '3:05' created even further illusion and mystery as the train station was extremely empty for 3.am, yet it would be unusual for the characters to be at the train station at 3.pm, again this highlights the audiences uncertainty of the plot. Flightplan showed the use of the films ident 'Touchstone Pictures', then followed by abstract titles which had footage of a train rushing past behind the titles, this created disorientation.
There were several other techniques I thought were interesting such as the conventional use of black and white contrasting colours and the use of the stairs. The negativity of the mans death contrasted with the child bedroom. One technique which highlighted this contrast was the use of the visual bridge, plane shadows were shown moving over the court yard and then into the child's room from the night light. Me and my group member may decide to use a visual or audio bridge in our extract as we thought it was extremely effective.
