There’s been a lot of news coming from Disney’s D23 expo this weekend, so let’s catch up on the fact that Game Of Thrones’ Kit Harington, better known as Jon Snow, is joining the Marvel Cinematic Universe.

Harington will join his Game Of Thrones buddy, Richard Madden, in Chloé Zhao’s The Eternals, to play a character called Dane Whitman. This is intriguing for a whole bunch of reasons we’ll unpack here.

Dane Whitman, as all good comic book readers know, is the alter ego of the Black Knight, a character who wields a mystic ebony sword (with a blood curse) and a long-time member of The Avengers.

In more recent years, the Black Knight’s story was closely connected to Marvel’s UK superhero, Captain Britain, a character that the geek rumor mill has been in overdrive about for the past couple of years, suggesting that Marvel are gearing up to bring him to their Cinematic Universe.

While Whitman and the Black Knight have been connected to The Eternals in the comics (via a romantic entanglement between Whitman and Eternal, Sersi), you might begin to question why they’re being brought together for the movies, it seems unlikely someone with Harington’s star power would be brought in for a one-off cameo, and…

Well, that’s a lot of conjecture and putting two and two together to make five, but hey, what else can we do with so little solid information coming from Marvel at this early stage!?

Will this be a full-on introduction for the Black Knight? Will that lead to a Black Knight movie or series (Harington would fit in nicely with the other Disney Plus Marvel shows)? Will that open up a doorway to introduce Captain Britain? Will the UK cease to exist after Brexit?

Feel free to add your tuppence ha’penny worth’s of opinions in the comments below.

Meanwhile, the Game Of Thrones alumni will join Angelina Jolie, Kumail Nanjiani, Lauren Ridloff, Brian Tyree Henry, Salma Hayek, Lia McHugh, and Don Lee.

The Eternals will hit your local cinema next November.
