Kit Harington, known for his role as Jon Snow in ‘Game of Thrones’, joined the Marvel Cinematic Universe (MCU) in ‘Eternals’ as Dane Whitman/Black Knight. While his character had a minor role in ‘Eternals’, a post-credits scene hinted at his future prominence in the MCU, particularly in the upcoming ‘Blade’ movie. However, ‘Blade’ has faced numerous setbacks, including director and screenwriter changes, casting doubt on Harington’s return as Black Knight. Additionally, the box office performance of ‘Eternals’ has made a sequel unlikely, further complicating Harington’s MCU journey.
