Conventions of Psychological thrillers

• Clever and unusual plots making the audience think in depth, often back to front by using flashbacks avoiding the typical structure of films. (Such as action) Twists used at the end to make the audience doubt themselves 
• often end on a cliffhanger , not always a resolution 
• question reality
• unusual heros, different from most films where hero is stereotypically big, strong, handsome etc..
• unusual dark themes
• focus on one psychological dimension
• typical narrative structure not used
• parallel edits, use of flashbacks
• characters in conflict with their own mind due to psychologically related problems/handicaps
• 2 characters preying on each others minds
• Danger is on a mental level rather than physical
• Mysterious
