Christine Tremarco wins best supporting actress at BAFTA TV Awards

christine tremarco won best supporting actress at the BAFTA TV Awards for her performance in Adolescence. The win gives a 30-year screen veteran a major industry prize for one of the year’s most discussed dramas.

Adolescence and Manda Miller

Tremarco played Manda Miller, the mother of Jamie Miller in Adolescence. Jamie Miller was accused of killing a female classmate in the series, placing her character inside the show’s central conflict rather than on its edge.

The award also lands after a run that has kept Tremarco visible across British television. She was praised for The Responder in 2025, and before that she was best known for Waterloo Road, Casualty and Emmerdale, with earlier credits including Fat Friends, Little Boy Blue, Clink and Wolfe.

From Kirby to BAFTA

Tremarco was born and raised in Liverpool and attended Holly Lodge Girls College. She was scouted in a school play and invited to a drama school, then made her on-screen debut at 15 after being spotted by a casting agent.

That early start is part of what gives this win its edge. She has spent more than 30 years on screen, moving from Priest and The Leaving of Liverpool to later film and television work, and this BAFTA places her among performers whose careers have lasted long enough for the prize to feel like recognition of the full body of work, not just one role.

Stephen Graham and the cast

The social reach of Adolescence also sits behind the result. Tremarco grew up in Kirby with Stephen Graham, and she said, "It was really emotional, from kicking around the streets of Kirby to the Emmys," and, "We’re just two kids from a council estate, I’m so proud of him."

She added, "I was so proud of Owen," and "He’s only 15, you know, and to get up there in front of all those people…" She also said, "I was just so delighted for all of our Adolescence team, cast and crew."

For readers tracking where the attention goes next, the practical answer is simple: the BAFTA has shifted Tremarco from a dependable television presence into award-winning status, while Adolescence keeps its cast inside the awards conversation. That is the kind of recognition that travels well across casting rooms, and it is now attached to her name.
