Kit Harrington's Dane Whitman was considered for a cameo appearance in the Disney+ series, according to Moon Knight head writer Jeremy Slater.
Moon Knight head writer Jeremy Slater explains that Kit Harington's Dane Whitman, nicknamed Black Knight, was almost brought in for the Disney+ series. In 2021's Eternals, Harington's character first appeared as Sersi's love interest. Meanwhile, Oscar Isaac appeared as the complicated enforcer of the Egyptian god Khonshu in Moon Knight, which just finished its 6-episode run.
Harington's character was first introduced in Chloé Zhao's Marvel epic as an unassuming scientist and historian at the London Natural History Museum who falls in love with Sersi, unaware of her true nature as a member of the powerful Eternals. Dane only had a minor part in Eternals, but the film's post-credits scene hinted at a far bigger MCU future. He was given the Ebony Blade by a deceased ancestor, as in the comics, foreshadowing at his transformation into Black Knight. Blade, played by Mahershala Ali, made a cameo appearance in the scene. While Harington's MCU future remains unknown, one of Moon Knight's writers has indicated that Whitman may have returned to the MCU sooner than fans imagined.
Episode 6 of Moon Knight introduces a new MCU Avengers team.
Slater revealed some early facts about Moon Knight's development in a recent interview with ComicBook.com. Because of his work at the Perfect History Museum, Slater believes a Whitman cameo would be a natural fit for the series. Whitman would have to be seen becoming the Black Knight and playing a larger role in Moon Knight's first two episodes, according to the head writer, because Slater thought a simple, fast encounter between him and Isaac's Steven Grant would be a waste of Harington's appearance. Take a look at Slater's account below.
The Eternals themselves were considered for a flashback throughout the development of the series, thus Whitman wasn't the only Eternals cast member considered for a Moon Knight cameo. The superpowered artificial beings were considered for a cold-open flashback that would depict the team of heroes assisting Khonshu's (voiced by F. Murray Abraham) previous Avatar, Alexander the Great, in sealing away Ammit (voiced by Saba Mubarak) in Ancient Egypt, according to Slater in a previous interview. However, bringing the squad into Moon Knight would have been too costly due to the cost of the sequence. Slater agreed that future appearances and development should be saved for the MCU's later chapters.
Moon Knight stood out among other Marvel Disney+ series because it had little ties to the MCU, save from a few references, allowing it to create its own tale separate from any ongoing plots. Many members of the cast of the show are open to crossover potential in future MCU projects beyond Moon Knight, so Steven and Dane could yet meet. While Whitman's future is unknown, it's probable that Harington will also appear in Ali's Blade picture.
