Jonas Alexander Abramowitz Arnby debuted with the critically acclaimed feature When Animals Dream, which premiered in Cannes Critics’ Week and competed for the Camera d’Or. The film — a stylish, atmospheric coming-of-age story about a teenage girl who discovers she’s a werewolf — went on to screen at the BFI London Film Festival and more than 30 festivals worldwide, and was released by Altitude Film Distribution (UK) and RADiUS-TWC to outstanding reviews.

Arnby’s second feature, Exit Plan / Suicide Tourist, an existential mystery thriller starring Nikolaj Coster-Waldau, premiered at the Sitges Film Festival and Zurich Film Festival.

He was the lead director of THE UNIFORM, a six-part thriller for Fremantle and Miso Film, which at the moment is a major national broadcast success and has since been sold to several international territories, including the BBC. The series was awarded the 2026 Golden Nymph for Best TV Series at the Monte-Carlo Television Festival.

He is now lead directing SIDE EFFECTS, a new TV 2 drama series for Fremantle, continuing his close collaboration with premium Scandinavian broadcasters and international production partners.

Most recently, Arnby directed and executive produced all six episodes of BLOOD CRUISE for SVT / CBS — a stylized, pulpy Nordic horror series which premiered in the Nordics to great reviews.

Before that he developed, directed and executive produced the eight-part Sky/Showtime drama VERONIKA, a character-driven, psychologically tense series that became a major critical and audience success across Scandinavia. Praised for its bold aesthetic and strong performances, the show proved such a success that it was renewed for both a second and third season.

His additional television work includes The Helicopter Heist for Netflix — a fast-paced, high-end true-crime series; the concluding episodes of War of the Worlds for Urban Myth Films/Fox/Disney+ (starring Gabriel Byrne), where he steered the series toward its final, emotional endgame; and the neo-noir crime drama Darkness: Those Who Kill for BBC4/Viaplay, which he helped reboot into its most-watched season.

Before moving into long-form storytelling, Arnby honed his craft directing award-winning commercials and music videos worldwide — a visual foundation that continues to shape his narrative work.
