Nathan Barr (True Blood, The Americans, Hostel, The House with a Clock in Its Walls, The Great,Cabin Fever, Carnival Row) has composed the original music for the upcoming Prime Video original series 56 Days. The show is developed by Lisa Zwerling & Karyn Usher based on Catherine Ryan Howard’s bestselling novel of the same name and stars Dove Cameron, Avan Jogia, Karla Souza and Dorian Missick. The 8-part thriller revolves around the discovery of an unidentified body – brutally murdered and intentionally decomposed – and intercuts between an intense single day in the present investigation and the trajectory of the involved young lovers’ affair in the past. Zwerling & Usher are also executive producing the Amazon MGM Studios production with Atomic Monster’s James Wan (The Conjuring, Aquaman), Michael Clear (Malignant, MacGyver) & Rob Hackett (Teacup, I Know What You Did Last Summer). Barrr has previously scored the Zwerling- and Usher-produced Starz limited series The Rook. 56 Days will premiere on February 18, 2026 on Prime Video.
Barr is also expected to return to score the fifth season of Apple TV’s The Morning Show. He has also recently co-scored Stephanie Laing’s feature Tow (with Este Haim), which premiered at this year’s Tribeca Film Festival and has been picked up by Roadside Attractions for a theatrical release in 2026.
