Three spoilers for House of the Dragon will be revealed later.
Three episodes into the series, Eagle-eyed House of the Dragon fans noticed the show's first CGI error.
King Viserys is suffering from an infection that is ravaging his flesh, according to viewers. In episode three, which takes place two years after the previous installment, the King's illness has clearly progressed, leaving him missing two fingers on his hand.
For the wrong reasons, fans' attention was drawn to the missing fingers, as Viserys actor Paddy Considine is seen wearing a green glove in one scene, which has evidently been missed by the editing crew.
People were quick to notice the flaw and shared the photo which can be seen below.

This isn't the first time that Game of Thrones producers have experienced editing difficulties. Fans immediately recognized the famous coffee cup seen in front of Daenerys Targaryen in season 8 of the fantasy show.
The outcry over the internet has even led HBO to release a rouge coffee cup. "The latte that appeared in the episode was a mistake. Daenerys had ordered a herbal tea," the network said.
During a battle beyond the wall, an editing error in season 7 resulted in a character fighting thin air rather than the army of the dead.
Viserys' green fingers are likely to fade from the episode sooner than expected, and are unlikely to detract much from the new program, which is currently receiving positive feedback from fans.
House of the Dragon airs on HBO Sundays and Mondays on Sky Atlantic and NOW in the United Kingdom. Season 2 has been confirmed. Seasons 1-8 of Game of Thrones are available on DVD and Blu-ray.
