Watch Online: Addition (2026)

Addition (2026) promises to be a refreshingly original drama that explores the intricate mind of a brilliant mathematician navigating life's chaos through the lens of numbers and obsessive-compulsive patterns. Directed by Marcelle Lunam and written by Becca Johnstone, this Australian production offers an intimate character study with a supernatural twist. With Teresa Palmer headlining an exceptional ensemble cast, "it all counts" — and so does your anticipation for this uniquely captivating film.

Understanding Addition: A Character-Driven Drama

At the heart of Addition (2026) is Grace Lisa Vandenburg, a Melbourne-based mathematician whose life revolves around numbers — literally. Grace suffers from arithmomania, a compelling obsessive-compulsive disorder that compels her to count everything obsessively, always three times to guarantee accuracy. From the poppy seeds adorning her morning cake to the individual bristles on her toothbrush, nothing escapes her compulsive counting rituals.

In a world that feels increasingly unpredictable and sometimes tragic, Grace's mathematical obsessions provide an anchor — a way to impose order and control on the chaos surrounding her. Yet despite her singular focus on numbers, she attempts to maintain genuine human connections: caring moments with her mother and sister, cherished time with her beloved niece Larry, and an unusual but meaningful relationship with the manifestation of Nikola Tesla, history's legendary inventor and engineer, who serves as her closest confidante.
