The Game of Thrones star Kit Harington will portray Dane Whitman, who will become the Black Knight and wield the mighty Ebony Blade. We haven't seen Harington's character in the film's set but in a new photo, some fans actually believe that the blurry image is Black Knight's Armor.
Looking at the circled figure above, it may be just a crew member since it's hard to say if this is really Black Knight's armor. Dane Whitman will likely have a major role in the MCU, with Gemma Chan's new character Sersi. The Eternals is one of two Marvel films that will be released in 2020, after Black Widow solo movie after her death in Avengers: Endgame.
The Eternals will hit in theaters on November 6th, 2020.
