"As one of the most prolific and best loved genres in film there is an overabundance of quality cinematic thrillers. Amongst so much competition it is easy to miss out on hidden gems. What is more there are so many flavours of suspense, tension, chase, twists and all the other ingredients that make a good thriller. There are also so many different combinations of genre, tone, and theme, as well as the expansive span of cinema history to choose from.
This list will endeavour to present a host of thrillers that for one reason or another are underseen and underappreciated. Some are from well-known directors whose more famous work in the genre overshadows these offerings. Others are more contemplative character-based thrillers which might be lost in the flashier action-packed alternatives. A few are genre hybrids that are sometime hard to categorise but are thrillers to their core."
