House Of The Dragon fans spot incredible Gavin and Stacey cameo

Game of Thrones was filled with familiar faces from British TV, and its prequel House of the Dragon is no different.

One of the latest unexpected appearances that has fans talking is a star from the beloved sitcom Gavin and Stacey.

Yes, a number of eagle-eyed viewers spotted that none other than Steffan Rhodri appeared in the first and latest episode of the hit HBO fantasy show.

For those not in the know, Rhodri portrayed Dave Coaches in Gavin and Stacey, the guy who ran the coach company on Barry Island.

Needless to say his character looks rather different in House of the Dragon, as he's taken on the role of the Hand of the King Ser Otto Hightower’s brother, Ser Hobert Hightower.

Taking to Twitter to share their surprise at his transformation, one fan joked: "Can’t believe wee Dave Coaches is running about Westeros nowadays acting as if he doesn’t love the dodgems!"

Following the release of the third episode over the weekend, another said: "Seeing Dave Coaches swanning around Kings Landing was a sight I didn’t expect to see this evening."

"Seeing Dave coaches on ep 3 has made my life," added a third, while a fourth said, "Just realised that Dave Coaches is Lord Hightower in #HouseoftheDragon."

Others just enjoyed seeing unexpected names from British TV pop up as they did with the show's predecessor.

That includes this viewer who wrote: "Watching #HouseoftheDragon or rather, playing 'what's this guy from?' and enjoying the British television universe crossovers of the dad from Fleabag, Dave Coaches from Gavin & Stacey, and the hot twins from Shameless."

While fans are certainly happy to see old Dave back on their screens, others are sad that some actors are set to bow out halfway through the season.

When the timeline jumps forward, a number of the younger cast are set to be replaced with older actors, including Emma D’Arcy taking over from Milly Alcock as Princess Rhaenyra Targaryen.

The same goes for Alicent Hightower, played by Emily Carey, with Olivia Cooke taking over in later episodes.

Leana (Nova Foueillis-Mosé) and Laenor (Theo Tate) Velaryon will also be replaced, with actors Nanna Blondell and John MacMillan taking on the roles respectively.

While we have no doubt the newbies will shine in their portrayals of the characters, some viewers took to Twitter to share their upset.

One wrote: "Actual nightmare that Milly Alcock is leaving the show," while another commented: "They’re changing rhaenyra's actor midseason?? NOOOO she's the best part."

Another said: "Milly Alcock as young Rhaenyra Targaryen is one of the most perfect castings ever, i’ll never get over it #HouseOfTheDragon."

UK viewers can catch House of the Dragon on Sky Atlantic and NOW, while the show is available in the US on HBO and HBO Max.
