Yesterday i was researching the genre in which my group of Me, Elias, Jack and Ben B are doing. we will be attempting a crime thriller. so i foudn out a definition with some key features and some films along with directors of said films.
Crime thriller: This particular genre is a hybrid type of both crime films and thrillers that offers a suspenseful account of a
 successful or failed crime or crimes. 
These films often focus on the criminal(s) rather than a policeman. Crime thrillers usually 
emphasize action over psychological aspects. Central topics of these 
films include murders, robberies, chases, shootouts, and double-crosses are central ingredients. 
Some examples include The Killing, Seven, Reservoir Dogs, Inside Man, and The Asphalt Jungle.
