Fans praised Catherine Zeta-Jones after she used her Swansea accent in the trailer for Amazon Prime's Kill Jackie. The clip, posted on social media, offered the first clear sample of the actor speaking with the regional voice and prompted an immediate positive reaction online.

Filming returned Zeta-Jones to her native Swansea for some scenes, with other production locations including Bilbao, Lisbon and London. She plays Jackie Price, an extravagant jet-setter who, Amazon Prime says, is trying to stay anonymous after escaping a "dangerous past as an international cocaine dealer." The trailer provides the first look at that setup and at the show's tone.

Reaction focused on the accent. One viewer wrote that they loved hearing the "queen of Wales sounding Welsh," and another commented on Instagram, "her Welsh is out and I love it, can't wait." Observers flagged the choice as notable because Kill Jackie represents Zeta-Jones's first major screen role using a Welsh accent, a departure from many of her better known parts.

Zeta-Jones has framed the project as a chance to explore complex themes. She said she had been looking forward to a female-driven plot that "encompasses empowerment, identity and redemption," and has spoken of a strong connection to Wales, saying in her heart she "never really left." Her recent credits include Netflix's Wednesday and an Oscar-winning supporting role in Chicago.

The series adapts The Price You Pay by Nick Harkaway, published under the name Aidan Truhen. Óscar Jaenada and Damon Thomas are among the cast, with Tom Butterworth, known for Gangs Of London, serving as writer and showrunner. Kill Jackie is due to premiere on 2 October on Amazon Prime, giving viewers a full episode to judge how the accent and character work play out across the series.
