Conventions of the thriller genre

Using 'Flightplan' as an example, the conventions of thriller films can be explored.
A build up to the action was created by non diagetic sound coming from the train and innocent music to represent the child involved.
The character being alone at the train station created fear, apprehension, anticipation and an unsettling feeling.
The atmosphere is dark because it is nighttime and this makes it mysterious. It continues to stay dark throughout the opening and the turbulence of the plane builds tension. The innocent piano music plays over the turbulence.
Flashbacks are also included when the mother thinks back to when her daughter was pronounced dead.
A realistic setting is used to create a sense of 'the unusual' occurring within a normal setting. Here the realistic setting is an aeroplane. When the mother is looking for her daughter, the pace of both the music and the camera shots is fast.
