6 Best Thrillers Released Between 2000 and Now, Ranked for Suspense and Unsettling Stories

Thrillers Built on Suspense
The thriller genre spans many subgenres, offering audiences stories shaped by danger, suspense and tension. The films described here pair gripping narratives with ideas that linger beyond the immediate mystery.
Zodiac and Memento take different approaches to crime and uncertainty. One focuses on a decades-long investigation; the other makes viewers piece together events alongside a man with amnesia.
Zodiac’s Unresolved Manhunt
David Fincher’s Zodiac follows the search for the killer who terrorized the San Francisco Bay Area in the late 1960s and 1970s. Political cartoonist Robert Graysmith, played by Jake Gyllenhaal, becomes absorbed in the killer’s cryptic puzzles, straining his personal life as he pursues clues with journalists and police investigators.
Rather than ending with a capture or shootout, the film reflects the unresolved nature of a cold case. Its depiction of paperwork, calls, false leads and dead ends builds tension through the grind of the investigation. Performances from Gyllenhaal, Mark Ruffalo and Robert Downey Jr. anchor the story.
Memento’s Reverse-Told Mystery
Christopher Nolan’s Memento follows Leonard Shelby, played by Guy Pearce, who cannot form new memories and is trying to find his wife’s murderer. He tracks clues through Polaroid photographs, handwritten notes and tattoos.
The film alternates between color scenes that unfold in reverse and black-and-white scenes that move chronologically; the timelines meet at the end. This structure makes viewers share Leonard’s disorientation while raising questions about whether his methods for finding truth can also preserve lies and manipulation.
Key points
- Zodiac depicts a decades-long search for the Zodiac Killer without a neat resolution.
- The investigation in Zodiac strains the lives of the people pursuing the case.
- Memento follows Leonard Shelby as he searches for his wife’s murderer despite his amnesia.
- Memento’s color and black-and-white timelines converge at the film’s conclusion.
