The mystery thriller genre has seen a quiet but meaningful revival over recent years, moving beyond traditional whodunits and noir clichés to include psychological depth and complex character work. Riz Ahmed mystery thriller Relay adds to this trend, earning a 78% rating on Rotten Tomatoes shortly after its theatrical release on August 22, 2025. The film features Ahmed as Tom, a professional fixer who arranges payoffs for corrupt corporations, and Lily James as Sarah, a client whose motives blur the lines between ally and threat.
Directed by David Mackenzie, known for Hell or High Water, Relay also includes supporting performances from Sam Worthington, Matthew Maher, and Victor Garber. The film premiered at the Toronto International Film Festival on September 8, 2024, and the screenplay by Justin Piasecki — initially called The Broker — was recognized on the 2019 Black List for unproduced scripts.
The Performance and Story Elements Garnering Attention
While some reviews point out that the film occasionally dips into familiar genre conventions, the majority applaud its tight pacing and suspense. Particular praise centers on Riz Ahmed’s portrayal of Tom, a layered character whose vulnerability adds emotional weight to the story. Likewise, Lily James delivers a compelling performance that balances charm with menace, creating dynamic tension between their characters.
David Mackenzie’s direction is credited for maintaining a taut atmosphere throughout, keeping audiences engaged despite the narrative’s occasional reliance on thriller tropes. The cast’s strong chemistry has been highlighted as a key factor in elevating the film’s impact beyond standard genre fare.
Implications of Relay’s Reception for the Genre
Achieving a Certified Fresh status on Rotten Tomatoes with a 78% rating is notable for a mystery thriller that is not based on existing intellectual property. This level of critical approval suggests that Relay is resonating with reviewers and could attract solid audience interest during its theatrical run. In an environment where genre films outside franchises often struggle to find visibility, Relay’s positive reception may help it stand out as a strong, character-driven entry.
Given Riz Ahmed and Lily James’ growing reputations for taking on emotionally rich, multifaceted roles, Relay might emerge as a sleeper hit that signals continued vitality for the mystery thriller genre. This resurgence reflects how such films are evolving, blending suspense with psychological insights that appeal to thoughtful viewers.
