Inside Her Role on Prime Video’s The Better Sister

Jessica Biel continues her fascination with psychologically complex characters in her latest role as Chloe Taylor in Prime Video’s The Better Sister.

Based on the novel by Alafair Burke, the series stars Jessica Biel opposite Elizabeth Banks as estranged sisters whose lives spiral after a murder accusation implicates Chloe’s son.

“I’ve been interested in these types of projects with complicated humans,” says Jessica Biel, reflecting on what draws her to the genre. “We’re all capable of goodness and evil. It’s hard to say, ‘I would never do that,’ because maybe I would.”

This ongoing exploration of moral ambiguity is at the heart of The Better Sister.

As Chloe, Jessica Biel plays a woman split between her polished public persona and her fiercely protective private instincts.

The tension between those roles forms the emotional spine of the series.

Finding Depth Through Maternal Instincts

As both star and executive producer, Biel found herself deeply connected to Chloe’s maternal arc. The character is willing to go to any lengths to protect her son Ethan (Maxwell Acee Donovan), especially when he’s accused of murdering his father, Adam (Corey Stoll).

“Everything she does is for Ethan, and I think every parent can relate to that on some level,” says Biel, who is herself a mother of two.

Filming emotionally and physically intense scenes required meticulous preparation and trust among cast members.

Biel credits rehearsal time and her scene partners for making difficult moments manageable. “Corey is an incredible scene partner. You feel safe with him,” she adds.

Balancing Trauma Onscreen and Real Life

Outside of set, Biel adopted rituals to decompress after long filming days. “I would listen to meditation or my weird frequency music that I have on Spotify,” she says. “Once I got home, I had to be a mom.”

That ability to switch gears between emotionally charged scenes and her real-world responsibilities was critical, especially during a project that trafficked in such heavy subject matter. Jessica Biel notes that the cast largely found their own methods for mental preparation, underscoring the personal nature of the work.

A Creative Reunion and a Personal Surprise

The Better Sister also reunited Biel with Corey Stoll, with whom she recently wrapped filming on the 2026 action-comedy Matchbox, based on the toy car brand. “We basically do have each other on speed dial,” Jessica Biel laughs.

The actors’ connection grew deeper off-camera, thanks to their children. “Our boys are really good friends now. We’re like parent buddies and call each other so our kids can FaceTime,” she shares. The unexpected friendship has turned into a lasting bond, one that extends beyond the set.

Looking Beyond the Darkness

After back-to-back thrillers—first 2022’s Candy, now The Better Sister—Jessica Biel is ready for a tonal shift. “I feel like it’s time to branch out a little bit,” she says. “Matchbox felt really cool and fun, something completely outside the psychological complex situation.”

Still, Jessica Biel isn’t ready to walk away from the genre entirely. “I can’t help but always love to watch and explore a psychological drama,” she admits.

Her upcoming slate reflects that balance: she’s in preproduction on Batso, co-starring Ethan Hawke and Daniel Radcliffe, and on Ursa Major, opposite Kid Cudi. Whether she’s stepping into darkness or lighter territory, Biel remains committed to roles that challenge and surprise her.
