Comercial Success
Both 38. The Girl on the Train, and 40. 10 Cloverfield Lane fall under the Psychological Thriller genre. Although most of the top grossing films of 2016 were of the Adventure, Action or Comedy Genre, these films still had a lot of success - their 2016 total gross both being over 70 million dollars.
With both of these films appearing in the top 40, shows that this type of film (with the storylines and conventions of psychological thrillers) have been both popular and successful in 2016.
On a bigger time scale, from 1995-2017, there is surprising many films in the top 25 movies that fall under the psychological thriller genre. Arguably within this list there are at least 5 films that would be considered a psychological thriller, however some of the films have more prominent conventions of more popular genres. For example the movie 'The Sixth Sense' , that impressively holds the 2nd spot, is a psychological thriller but is more known as a horror film, as its conventions fit also with this genre (e.g. ghost-story).
