What Movies and TV Shows Is Gwyneth Keyworth Known For?

Keyworth’s filmography is spread across major British series and independent films. Her earliest notable television credit came in 2009, when she played Marnie in two episodes of the E4 series Misfits, a show that helped launch a generation of young British actors. The same year, she appeared in The Sarah Jane Adventures.

Her Black Mirror appearance came in the season four episode “Hang the DJ” (2017), where she played Nicola, a character navigating a dating simulation system. The role placed her in one of the most talked-about anthology series in the world.

In Hidden (the Welsh-language crime drama also known as Craith), Keyworth took on the role of Megan Ruddock across eight episodes. The series aired on BBC One and S4C and earned her a BAFTA Cymru nomination for Best Actress in 2018.

Her claim to a role in Game of Thrones is often a point of confusion. According to her IMDb page and Wikipedia entry, she played Clea in the episode “High Sparrow” (season five). This is a minor part — a servant in the Faith of the Seven — but it is a confirmed, credited role. The confusion may stem from the fact that many Welsh actors appeared in the series, but Keyworth’s involvement is verifiable, if small.

Other Screen Credits

Additional roles listed across multiple sources include Death Valley, The Great Outdoors, Doctor Thorne, Wasted, Power Monkeys, Hinterland, Alex Rider, and The Crown. Her film work includes Elfie Hopkins (2012), Closer to the Moon (2014), and The Toll (2021).

The absence of family details in official sources may reflect a deliberate choice by Keyworth to keep that area of her life private, which is common among public figures.
