‘Josephine’ Teaser Trailer Unveiled: Channing Tatum and Gemma Chan Star in Sundance-Winning Psychological Thriller

Sumerian Pictures has unveiled the first teaser trailer for Josephine, the acclaimed psychological thriller from filmmaker Beth de Araújo, giving audiences their first proper glimpse into one of the year's most talked-about independent films. The movie premiered at the 2026 Sundance Film Festival, where it made a major impact by winning both the Audience Award and Grand Jury Prize, before going on to screen in the Main Competition at the Berlin Film Festival.

At the heart of Josephine is an emotionally devastating story about childhood trauma and its impact on an entire family. The film follows eight-year-old Josephine, who accidentally witnesses a heinous crime in Golden Gate Park. Unable to process what she has seen, the young girl begins acting out violently as she attempts to protect herself from the fear and emotional turmoil that follow.

The teaser hints at a tense and deeply unsettling journey as Josephine's behaviour begins to affect her family. Her parents, played by Channing Tatum and Gemma Chan, struggle to understand what their daughter is going through while simultaneously confronting their own fears about the situation. What begins as an attempt to help Josephine cope gradually develops into a much larger emotional conflict surrounding justice, safety, parenting and the consequences of trauma.

Making her feature debut, newcomer Mason Lily Reeves takes on the challenging title role of Josephine. Her performance has already drawn significant attention following the film's festival run, with critics praising the emotional weight she brings to a character forced to deal with experiences far beyond her years. The film also features Phillip Ettinger, Syra McCarthy and Eleanore Pienta in supporting roles.

Written, produced and directed by Beth de Araújo, Josephine marks her second feature film following Soft & Quiet. The filmmaker once again explores uncomfortable and emotionally charged subjects, but this time through the perspective of a child and the family struggling to find a way forward. The result appears to be a psychological thriller that relies as much on emotional tension as it does on suspense.

The film's impressive festival journey has already positioned it as a major title in the independent cinema space. Its Sundance wins, followed by its selection for the Berlin Film Festival's Main Competition, have helped build strong word of mouth around the project. The early response has particularly highlighted de Araújo's direction and the performances of Reeves, Tatum and Chan.

Interestingly, Josephine brings together a striking combination of emerging and established talent. While Mason Reeves gets a major breakout opportunity in the title role, Channing Tatum and Gemma Chan step into dramatically intense territory as parents dealing with an unimaginable situation. Their performances are expected to add another layer of complexity to a story that examines how a family attempts to heal when there are no easy answers.

Rather than presenting trauma simply as a plot device, Josephine appears to explore how a single horrifying incident can change the dynamics of an entire household. The film's focus on Josephine's behaviour, her parents' response and their search for a sense of security gives the story a deeply human dimension beneath its thriller framework.

With its acclaimed festival run, powerful premise and an increasingly buzzed-about central performance, Josephine is shaping up to be one of the more intriguing psychological dramas of 2026. Sumerian Pictures is set to bring the film to audiences on November 20, 2026, giving moviegoers a chance to experience Beth de Araújo's unsettling and emotionally charged vision on the big screen.
