Sterling Point Cast: Full Character Guide to Prime Video’s New Teen Drama

The Sterling Point cast brings together rising young actors and familiar screen names for a coming-of-age mystery built around a remote Canadian island, a disputed inheritance and a family secret that changes everything. Ella Rubin leads the Prime Video series as Annie Jacobson, a driven New York teenager whose carefully planned summer is interrupted when she and her twin brother Connor inherit property from the grandfather they barely knew.

When Annie reaches Sterling Point, she meets Ramona, another teenager who claims the island and its home belong to her too. That discovery opens the door to a hidden family connection, a new circle of friends and a romantic conflict involving two very different boys. Prime Video will release all eight episodes globally on August 5, 2026, allowing viewers to watch the complete mystery without waiting for a weekly finale.

The show should appeal to viewers who follow young-adult adaptations and relationship dramas. Readers interested in similar material can also see our Off Campus series review, which explores another romance-driven story aimed at a younger audience.

Ella Rubin as Annie Jacobson

Ella Rubin plays Annie, the central point-of-view character. Annie is intelligent, ambitious and comfortable when life follows a clear plan. The inheritance forces her into the opposite situation. She travels from New York to a place where the rules, relationships and even her family history are uncertain. Annie initially treats the island as a problem to solve, but the people she meets make it impossible to remain emotionally detached.

Rubin gives the series a lead who can handle romance, grief and mystery at the same time. Annie is not simply deciding which boy she likes. She is also confronting what her parents withheld, what her grandfather intended and whether the future she planned still fits the person she is becoming. Rubin previously appeared in Anora and The Idea of You, making Sterling Point one of her largest television roles so far.

Amélie Hoeferle as Ramona

Amélie Hoeferle plays Ramona, the girl Annie discovers living on the island. Ramona was raised by the grandfather whose death brings Annie to Sterling Point, so she has a personal claim to the property and a far deeper connection to its history. Her presence immediately turns an inheritance story into a family mystery.

Ramona and Annie are positioned as emotional opposites. Annie arrives with structure and expectations, while Ramona knows the island but has her own unanswered questions. Their developing sisterhood is the series’ most important relationship. Hoeferle is recognizable from Night Swim and The Hunger Games: The Ballad of Songbirds & Snakes, where she played Vipsania Sickle.

Keen Ruffalo as Connor Jacobson

Keen Ruffalo plays Connor, Annie’s twin brother. Connor shares the inheritance but does not respond to the island in exactly the same way as Annie. His more guarded, seemingly uninterested attitude gives him room to observe the group before revealing what he wants from the summer. Connor also helps the series explore how twins can experience the same family rupture differently.

Ruffalo is the son of actor Mark Ruffalo, but Sterling Point presents him as part of the young ensemble rather than treating the role as a celebrity cameo. Connor’s relationships with Ramona and the island community could become especially important as the family mystery develops.

Jacob Whiteduck-Lavoie as Ellis

Jacob Whiteduck-Lavoie plays Ellis, a quiet local who becomes one of Annie’s first connections to Sterling Point. He flies her to the remote property by seaplane and represents the part of the island that feels grounded, familiar and sincere. Ellis is immediately drawn to Annie, placing him on one side of the show’s central romantic triangle.

Ellis is more than the safe romantic option. His knowledge of the community and his relationship with the other young residents make him a guide to the social world Annie has entered. Whiteduck-Lavoie brings warmth to a character whose apparent simplicity may be tested once the family secrets begin affecting everyone.

Daniel Quinn-Toye as Rory

Daniel Quinn-Toye plays Rory, the charismatic son of a wealthy local family. Rory hosts the kind of social gatherings that draw Annie deeper into the community, and he becomes the other major romantic possibility in her life. Where Ellis represents stability and openness, Rory challenges Annie and connects her to a more privileged, complicated side of Sterling Point.

Rory’s family owns a significant part of the town, which means his romantic storyline may also intersect with questions about land, money and control. Quinn-Toye previously gained attention through his stage work in Romeo and Juliet and has upcoming film roles, making Rory an important screen breakthrough.

Bo Bragason as Oona

Bo Bragason plays Oona, a bold British teenager who quickly becomes one of Annie’s most memorable new friends. Oona is confident, flirtatious and direct. She helps Annie operate a boat, introduces her to the group and pushes her to participate rather than watch from a safe distance.

Oona brings comedy and energy to a story that also deals with grief and buried family trauma. Bragason has appeared in The Jetty and Renegade Nell, and her performance gives Sterling Point the kind of scene-stealing best friend often found in classic teen dramas.

Jeffrey Dean Morgan as Joe

Jeffrey Dean Morgan appears in the recurring role of Joe. Full details about Joe’s connection to Annie, Ramona and the island are being kept limited before release, which suggests the character may be tied to the older generation’s secrets. Morgan’s casting adds dramatic weight and gives the show a recognizable adult presence alongside its younger ensemble.

Morgan is best known to many viewers as Negan in The Walking Dead. Our site also covers the wider franchise in the Walking Dead: Dead City Season 3 cast guide.

Jay Duplass as Steven

Jay Duplass plays Steven in a recurring role. Like Joe, Steven belongs to the adult side of the mystery. The series has not revealed every detail about him ahead of the premiere, but his involvement is likely to help explain the decisions made before Annie and Connor arrived. Duplass is known for Transparent, Togetherness and a long career in independent film and television.

Missi Pyle as Denise Ballantine

Missi Pyle plays Denise Ballantine, Rory’s mother. Denise is connected to one of the town’s wealthiest families, giving her influence over the social and financial world surrounding the teenagers. Her relationship with Rory may reveal the expectations he is trying to escape, while her interest in the island could complicate the Jacobson inheritance.

Nikko Angelo Hinayo as Sully

Nikko Angelo Hinayo plays Sully, the welcoming center of the younger friend group. Sully is described as someone who brings people together and creates a sense of safety, an important role when Annie and Ramona are trying to understand both each other and the community around them.

Mabel Strachan as Maple

Mabel Strachan plays Maple, the youngest member of the group and often its most reasonable voice. Maple’s intelligence and level-headedness allow her to notice details the older teenagers may miss while they are distracted by romance and personal conflict.

Elle-Máijá Tailfeathers as Kate

Elle-Máijá Tailfeathers plays Kate in a recurring role. The award-winning actor and filmmaker brings experience from projects including Night Raiders and Blood Quantum. Kate’s exact relationship to the island mystery has not been fully disclosed, so viewers should expect her role to become clearer as the eight episodes progress.

What Is Sterling Point About?

Sterling Point begins when Annie and Connor learn that their estranged grandfather has left them an island property in Canada. A cryptic letter pulls them away from New York and into a community their family never discussed. At the property, Annie finds Ramona, who believes she has an equal or stronger right to the same inheritance.

The discovery suggests that the grandfather created a final test, confession or attempt at reconciliation. Annie and Ramona must determine why they were kept apart, what happened in the previous generation and whether the island is a gift or a burden. At the same time, Annie becomes close to Ellis and Rory, two boys who represent different paths for her future.

Viewers drawn to complicated family relationships and young romance may also be interested in our coverage of My Life with the Walter Boys Season 3 and the upcoming Outer Banks Season 5 premiere.

Is Sterling Point Based on a Book?

Sterling Point is an original television series rather than a direct adaptation of a published novel. Megan Park created the series, while Josh Schwartz and Stephanie Savage serve as co-showrunners and executive producers. Their involvement explains why the project has been compared with The O.C. and Gossip Girl, although its island mystery and emotional focus give it a separate identity.

Where Was Sterling Point Filmed?

The series was filmed in Ontario, Canada, with the Lake Muskoka region helping create the wooded, waterside setting. The natural landscape is central to the story. Boats, cabins, remote roads and the distance from New York all reinforce Annie’s sense that she has crossed into a part of her family history that was deliberately hidden.

Will All Sterling Point Episodes Release Together?

Yes. Prime Video is scheduled to release all eight episodes on August 5, 2026. A full-season release should make cast searches, ending questions and explanations of the family connection particularly active during the first week.
