Review: The Inseparables at Finborough Theatre

There’s a lot to admire in The Inseparables, a new play by Grace Joy Howarth based on Simone de Beauvoir’s novella of the same name (you can read about that here), now playing at the Finborough Theatre. It’s an ambitious project to take on a reworking of this recently found novella. The story shines a light on the early life and friendships that helped shape one of the 20th century’s most radical thinkers. And whilst the production has flashes of beauty, particularly in its visuals and performances, it doesn’t quite land emotionally, mainly due to issues in the writing.

The source material is loosely autobiographical: Sylvie represents de Beauvoir and Andrée is based on her real-life best friend and confidante, Elizabeth 'Zaza' Lacoin. These two young women were pioneers in thought, pushing against social norms and having the kind of formative conversations that would later feed into de Beauvoir’s feminist philosophy. On paper, it’s fascinating. But on stage, the depth of their connection doesn’t fully come through. I didn’t quite feel their inseparable-ness, which seems like a bit of a problem when that’s the central premise. Teenage girl friendships can be some of the deepest, passionate bonds around, as intense as any romantic crush and I needed more of that emotional weight to make sense of the story.

The play unfolds in a series of short, fast-moving chronological scenes, jumping from childhood into their twenties. That structure might work on the page, but here it felt a little rushed and fragmented. It was hard to settle into any particular moment before we’d moved on again. It was also hard work as an audience member to keep up with what was going on and where we were in place and time. This also meant there wasn't time to get to any emotional depth between the two girls. We got glimpses of their radical spirit, but not enough of the raw, thought-provoking conversations that maybe fuelled de Beauvoir’s work.

That said, the production design is full of clever touches. Hazel Poole Zane’s set is minimal but effective: a simple window with lace curtains, a chaise longue, a dresser-turned-anything, and a couple of prop shelves - nothing flashy, but enough to give each scene a clear sense of place. The stage is small, but it never feels cramped, and the transitions are smooth and purposeful.

The standout design element, though, is the video projection by newcomer Jessica Brauner. These projections add real texture to the world of the play, transporting us from school chapels to rural idylls to domestic interiors. The stained glass effect is especially striking—there’s one moment in Act 2 where it’s used in combination with shadow dancers to contrast Andrée’s faith with Sylvie’s rebellion, and it’s genuinely beautiful.

Costume-wise, everything feels grounded in period—give or take the odd zip (a small detail, but zips weren’t really a thing until the 1930s!). Overall, though, the look and feel of the show is cohesive and well thought-out.

Performance-wise, the cast of four is strong. Lara Manela as Andrée is a real highlight—graceful, expressive, and consistently engaging. She brings a subtle wildness to the role that hints at something deeper beneath the surface. Ayesha Ostler as Sylvie is solid too, although I didn’t always feel the fire of Sylvie’s emotional or ideological journey. I think that's down to the writing as much as anything. Alexandre Costet-Barmada and Caroline Trowbridge both provide excellent support, juggling multiple roles with ease and nuance.

The real treats come in the movement sequences, choreographed by Daniela Poch. Andrée’s love of music, especially the violin, is beautifully rendered through dance. These moments could have veered into interpretive-dance cliché, but they don’t. They’re elegant, clear, and a lovely way of deepening the character. The music choices (by Flick Isaac Chilton) are also pitch-perfect, helping to break up the linear storytelling and evoke mood and time really effectively.

There’s also something genuinely exciting about the fresh talent involved in this production. Three of the cast are new graduates, two are French (which feels fitting, given the source material), and the video designer is also just starting out. It’s fantastic to see new artists being given this kind of platform, and I really hope we see more from them in future. Kudos to the Finborough Theatre for providing a platform for them to showcase their talents.

Am I glad I saw it? Absolutely. Despite its flaws, it’s made me want to read the novella and dig deeper into both de Beauvoir and Lacoin’s lives so in many respects, the purpose of the exercise has been achieved. It's also important to support new work to maintain the health of our theatre ecosystem.
