Gavin and Stacey called out for making simple 'mistake' in huge scene from finale

Fans of Gavin and Stacey are still recovering after that emotional rollercoaster of a finale on Wednesday (25 December), though there may have been something missing.

That's right, some fans think that Corden and co. made a massive mistake when it came to the near-flawless final episode.

It's been 17 years in the making, with the same cast and plot we've all been following, though they still managed to catch us off guard with one of the most emotional TV finales ever.

Spoilers ahead, if you hadn't guessed already.

Gavin and Stacey behind the scenes details emerge

From finally (almost) addressing the fishing trip to finding out that Sonia was still around, the episode was full of twists and turns that left several viewers in tears.

A lot of details have emerged about the Gavin and Stacey finale, as extras went off script, Gavin (Mathew Horne) refused to wear a West Ham kit, and Neil the Baby made a cameo at the wedding.

Some funny, some heartfelt, a number of moments made the episode - and the show as a whole - such a joy to watch, but fans found a reason to be slightly upset when they realised one detail about the final scenes.

It's finally over, what a ride (BBC)

After Smithy finally declares his love for Nessa (Ruth Jones) five years after her proposal, leaving Sonia at the altar, he legs it to the Southampton docks to stop her from spending six months in Curacao.

Luckily, things worked out after he got down on one knee and popped the question, though residents of Southampton were not impressed.

They had clocked on to the fact that the scenes at the docks were not filmed in the coastal city, revealing it looked nothing like the real docks in Southampton.

Gasp.

It turns out these scenes were filmed around 100 miles away in Newport Docks, Wales.

Obviously, this didn't stop 12.3 million people from watching the programme, though many Southampton residents took to social media to point out the detail.

One wrote: "Gavin and Stacey really tryna gaslight me into thinking that’s southampton docks. i know my city smh"

Another wrote: "Superb acting job by Newport Docks, playing Southampton docks on the #GavinAndStacey Christmas special."

Although a third shared: "I knew it wasn’t the real Southampton docks, but I don’t care!"

A record breaking farewell to Barry Island

The 12.3 million viewers that tuned in broke the record for the most watched TV episode across all channels in over 10 years, surpassing the number of 11.6 million viewers set by none other than - you guessed it - Gavin and Stacey with its 2019 Christmas special.

What an ending, though. Gavin and Stacey, you'll be missed.
