How a screenwriting homework assignment became an intimate ensemble film about loss, love, and the spaces between.

When Joe Anders sat down to complete a screenwriting assignment for his course, he didn’t imagine he was writing what would become his mother Kate Winslet‘s directorial debut. Yet “Goodbye June,” which premiered to emotional responses at its recent BAFTA screening, emerged from that exact moment – a young writer mining his own memories of his grandmother’s passing and transforming grief into art.

“I just remember standing in the room with her and my whole extended family and realising that all of these people had just come from or come for this one woman,” Anders recalls of his grandmother’s death. That memory became the emotional backbone of “Goodbye June,” a film that follows fractured siblings forced to reunite when their mother June (Helen Mirren) is dying of cancer.

An Unlikely Journey to the Screen

Anders, encouraged by his mentor Tammy Riley Smith to “write from the heart,” never intended the script for production. “I didn’t actually think… I just wrote it to see if I could write a good story,” he admits. Yet the screenplay’s authenticity attracted an extraordinary ensemble: Helen Mirren, Timothy Spall, Johnny Flynn, Andrea Riseborough, Toni Collette, and Winslet herself, who not only stepped behind the camera but also took on the role of Julia, one of June’s daughters.

The casting process itself bordered on surreal. Zeze Millz, who plays Nurse Angel, remembers receiving a call from her agent while on a bus: “How would you like to go for coffee with Kate Winslet next week?” After dropping her phone in shock, she learned about the film’s stellar cast. “And I go, that’s horrendous, but okay,” she laughs, referring to the subject matter.

Creating Space for Truth

What emerges most powerfully from the cast’s reflections is how Winslet created an environment unlike typical film sets. Drawing on years of acting experience, she understood what doesn’t work before discovering what does.

“There is nothing worse than when a director doesn’t know what they want,” Winslet explains. “So I did feel sort of well rehearsed in terms of knowing what actually doesn’t work more than what works, because the actors will always show you what works.”

Her approach was radical in its simplicity: give actors space, both literal and emotional. The film’s visual strategy reflects this philosophy. In the early sections, Winslet deliberately kept the camera back. “It was more important to be able to physically see the spaces between them all, because actually, in the case of Molly and Julia, they’re choosing to take that space. There are worlds of tension in those huge voids between them.”

Andrea Riseborough, who plays Molly, describes the experience with one word: “spacious.” She notes how Winslet “has noticed every last one” in film, creating trust both technically and creatively.

The Technical Magic of Invisibility

Winslet’s innovations extended to the technical realm. Working with sound designer Denise Yard, she hid microphones everywhere, eliminating the need for visible boom operators—her personal pet peeve as an actress. “I find it so hard to tune it out,” she confesses. “You’re doing an important scene, and the poor boom operator, you can see that their arms are shaking.”

The result? An unprecedented freedom. Helen Mirren noticed immediately: “Do you know the sound department? They’re very invisible. It’s really quite extraordinary.”

This extended to how Winslet worked with the children, who were all individually miked. Rather than having them learn lines, she let them play, using their character names throughout filming. “We just had hand signals. And so they’re just playing away, fully in character, and it was all usable,” Winslet explains. Months after filming, at a cast screening lunch, the children were still using their character names.

The Hospital That Breathes

The film’s hospital setting presented another creative challenge. “It really mattered enormously, because when you’re trying to tell a story that is ultimately about a family and about life as much as it is about loss, and there’s so much humour, it would have been disastrous if we’d had the whole thing feel very stark and white and bright,” Winslet explains.

They found inspiration in a derelict art deco hospital at Ravenscourt Park, with its distinctive green and red lino floor, polished to a shine, and crucially, light pouring through glass doors at every corridor’s end. This became the template for June’s room, built on stage with deliberately low ceilings to match the intimate, provincial feel of hospitals outside London.

Characters Who Live in the Margins

The screenplay’s greatest achievement may be how it gives each character their own truth. Timothy Spall’s Bernie is a masterclass in what’s left unsaid. “He’s in a constant state of being cancelled by the family, which he plays up to. He looks like he doesn’t give a toss about anything, but ultimately, down in the centre of this character, is absolutely riddled with fear, despair.”

There’s a moment, Spall notes, where Bernie simply asks June, “You’re all right, you?” She doesn’t even look up. “I think if the audience pays attention, there is 50 years of love and five years of going through this slow demise.”

Johnny Flynn found personal resonance in Connor, having lost his own father as a teenager. “I was there sort of supporting my mum and being around for my younger sister, so a lot of the story resonated, just those spaces of waiting, of listening to diagnostics and trying to crack jokes to keep people’s humour up.” It’s the only script, he admits, that made him cry.

Toni Collette’s Helen is the family’s “black sheep,” the eldest child with “a bit of abandonment wounding,” a woman “searching, seeking, improving, fixing, trying to better herself.” Yet Collette loves that “she’s so joyous, I love that she wears yellow, I love that she’s sunshine. But I also love that there’s real depth there.”

The Reluctant Matriarch

Helen Mirren, one of cinema’s most celebrated actresses, initially resisted the role. “I did not want to play June. I did not want to be dying of cancer in a bed,” she admits. But the ensemble nature of the piece -reminiscent of her beloved stage work – ultimately drew her in.

What convinced her further was watching Winslet on set during filming, seeing “this woman absolutely knows the technique of film.” In one scene, Mirren watched Winslet carry a baby, stay in character wearing reindeer antlers, and direct the camera simultaneously. “I looked at her and I went, oh, my God, I love you so much.”

A Love Letter to Nurses

For Millz, playing Nurse Angel became a tribute to her mother, who has been a carer most of her adult life. Winslet arranged for her to meet several nurses, including two from a cancer ward. One piece of advice stayed with her: “When we get a new patient, the first thing I think is, we have to get it right.” That belief, she decided, would be Angel’s core.

The Work Behind the Work

Perhaps Timothy Spall articulated it best when discussing his cast mates: “When you hear them talk, you realise how deep, what deep thinkers they are about these characters, about how much work they’ve all done before they come on a set. Contrary to popular opinion, actors identify all their ego mainly with that… They’re brilliant actors, not just because they’re good at showing off. They’re brilliant because they’ve got brilliant minds and they care and they understand the map of the human heart.”

This depth of preparation, combined with Winslet’s leadership, created what Flynn called “the safest set I’ve ever been a part of.” The entire crew felt like family, with many being people Winslet had worked with before and actively promoted to head of department roles.

What Remains

“Goodbye June” tackles a subject everyone will face – loss, grief, and the complicated dynamics of family – with a rare combination of honesty and warmth. It’s a film about people who have “cast themselves in roles” within their family, as Spall notes, and what happens when death forces them to drop those masks.

Joe Anders, still somewhat stunned that his homework assignment became this film, couldn’t believe it “was so wise beyond his years,” according to Riseborough. But perhaps that wisdom came from the simplest place: a young man remembering his grandmother and recognising that in the end, we all gather for the people we love.

As for Winslet, the cast’s unanimous verdict is clear. “I consider [her] one of the best actor directors I’ve ever worked with,” Spall declares. And based on this first effort, it’s a journey audiences should follow with eager anticipation.
