Fans of Gavin and Stacey were left overjoyed with the sitcom's finale on Christmas Day. The final-ever episode became the most-watched show on December 25 with 12.5 million viewers tuning in to see what creators Ruth Jones, who stars as Nessa, and James Corden, who plays Smithy, came up with for the highly-anticipated conclusion - and it did not disappoint.
Viewers saw title characters Gavin and Stacey Shipman, played by Mathew Horne and Joanna Page, reunite with the rest of the clan for one final adventure, which ended with Nessa and Smithy's own wedding day after a disastrous engagement. And fans did not miss a trick with the subtle references, inside jokes and surprise appearances.
One actress viewers were delighted to see in the final episode was Anna Maxwell Martin, who recently wowed ITV viewers with her portrayal in Until I Kill You. As Smithy stood at the alter, about to marry his girlfriend Sonia, played by Laura Aikman, it was Anna who, as the celebrant, was about to declare them husband and wife before best man Gavin's objection.
Viewers were ecstatic about her appearance, with many taking to X to share their excitement. One wrote: "Anna Maxwell Martin as the celebrant tho [clapping emoji]" while another penned: "Anna Maxwell Martin! Now that's the cameo we came for!". A third said: "goddess anna maxwell martin in gavin & stacey i’m OBSESSED". Over on forum mumsnet, one anonymous user declared that the actress was the best part of the finale.
