(VIDEO) Dove Cameron Thriller Series ’56 Days’ Tops Prime Video Charts, Hits No. 1 in U.S

Former Disney Channel star Dove Cameron has scored a major streaming hit with her new Prime Video thriller series *56 Days*, which claimed the No. 1 spot on the platform’s U.S. rankings shortly after its February 18, 2026, premiere, dethroning established shows like James Patterson’s *Cross* and drawing widespread attention for its twisty erotic mystery plot.

The eight-episode limited series, adapted from Catherine Ryan Howard’s bestselling novel of the same name, quickly surged to the top of Prime Video’s most-watched list in the United States within days of release, according to Amazon’s internal charts and third-party trackers like FlixPatrol and Reelgood. It displaced Amazon’s own *Fallout* adaptation and other heavy-hitters, fueled by strong word-of-mouth, Cameron’s fanbase and the appeal of its high-concept premise: a whirlwind romance that ends in a gruesome crime, reconstructed over exactly 56 days.

In *56 Days*, Cameron stars as Ciara Wyse, a working-class newcomer to Boston who meets charming, affluent Oliver Kennedy (Avan Jogia) in a supermarket. Their intense, fast-moving relationship unfolds in steamy, secretive scenes until detectives Lee Reardon (Karla Souza) and Karl Connolly (Dorian Missick) discover a decomposed body in Oliver’s luxury apartment bathtub. The narrative jumps between the lovers’ passionate early days and the police investigation, unraveling lies, secrets and dark motives on both sides.

The show premiered February 18, 2026, with all episodes dropping at once, encouraging binge-viewing. Early viewership data shows it climbing Prime Video’s U.S. charts rapidly, reaching No. 1 by late February and maintaining momentum into the weekend. Globally, it ranked in the top 10 in multiple markets, including the UK, Canada and Australia. The series earned an 86% audience Popcornmeter score on Rotten Tomatoes, reflecting solid viewer approval despite mixed critical reception that noted predictable twists but praised the leads’ chemistry and tension.

Cameron, 29, known for roles in *Descendants*, *Liv and Maddie* and recent projects like *Schmigadoon!*, delivers a layered performance as Ciara, blending vulnerability with menace. Jogia, seen in *Victorious* and *Zombieland: Double Tap*, brings charisma and unease to Oliver. The cast also features strong supporting turns from Souza and Missick as the detectives piecing together the timeline.

Directed by Alethea Jones and executive produced by James Wan, *56 Days* leans into psychological thriller elements with erotic undertones, echoing shows like *You* and *Tell Me Lies*. The limited run keeps pacing tight, with flashbacks revealing red flags in the couple’s relationship while the present-day probe builds suspense toward the crime’s resolution.

The series’ success highlights Prime Video’s push into original thrillers amid stiff competition from Netflix and Hulu. Amazon has ramped up acquisitions of book adaptations, with *56 Days* benefiting from the novel’s pre-existing fanbase and timely release in a crowded winter slate. Promotional efforts included a teaser trailer emphasizing “every good love story needs a murder,” Cameron’s social media posts and cast interviews highlighting the story’s addictive quality.

Viewers and critics have noted the show’s bingeable format and strong performances, though some reviews pointed to familiar tropes in the genre. RogerEbert.com called it “short on heat” despite solid acting, while Variety praised Cameron’s “enchanting” turn in a “surprising erotic thriller.” Collider described it as “the perfect weekend binge for mystery fans,” citing its red-flag-filled romance and satisfying reveals.

The No. 1 ranking underscores Cameron’s growing draw as a leading lady beyond teen roles, with her music career and social media presence (millions of followers) boosting visibility. The series also features a soundtrack contribution from Cameron, who has hinted at new music releases tied to her acting projects.

As *56 Days* continues dominating charts, Prime Video may see sustained momentum into March. No renewal has been announced for a second season, given its limited-series format, but strong performance could spur interest in similar adaptations.

For fans of twisty thrillers and star-driven dramas, *56 Days* has emerged as February’s breakout streaming success, proving Cameron’s versatility and Prime Video’s strength in genre programming.
