Goodbye June cast: Every character featured in the Christmas family drama and the actors behind them

Goodbye June was written by Joe Anders and directed by Kate Winslet. The film is a family drama based on four adult siblings reuniting around their terminally ill mother June, during the Christmas season, exploring grief, love, and complicated family relationships. Goodbye June was released in the United States on December 12, 2025, in select theaters and then began streaming on Netflix on December 24, 2025. 

It follows a group of estranged adult siblings who reunite at their childhood home during Christmas to be with their terminally ill mother, June. As they gather under one roof, unresolved tensions, buried resentments, and long-standing emotional wounds resurface. Over the course of the visit, the family confronts grief, love, and forgiveness, gradually reconnecting while preparing to say goodbye.

Goodbye June was filmed entirely in London, United Kingdom, with most scenes shot across the city and surrounding areas. The production transformed St. Mary’s University in Twickenham into the fictional Princess Mary Cheltenham Hospital, using classrooms and hallways as medical settings enhanced with props and fake snow. 

Additional interior and driving scenes were captured on soundstages at Garden Studios in London, while outdoor sequences showcasing the city’s Christmas charm and local park settings were also filmed nearby, grounding the family drama in authentic British locales.
