• Marvel's "Eternals" had the lowest box office performance of any Marvel Cinematic Universe (MCU) film, earning only $164 million domestically and $402 million globally. This was a significant disappointment for the studio, as the film featured a diverse cast and was directed by the Oscar-winning Chloé Zhao.

• Despite the underwhelming performance of "Eternals," Marvel is planning to bring back the character Dane Whitman, played by Kit Harington, in future MCU projects. Whitman is the human alter ego of the superhero Black Knight, and his introduction in "Eternals" was seen as a setup for a larger role in the MCU.

• The article suggests that the poor box office performance of "Eternals" may have been due to a combination of factors, including the film's complex storyline, the unfamiliarity of the Eternals characters to general audiences, and the ongoing impact of the COVID-19 pandemic on the movie industry. However, Marvel's decision to continue developing the Black Knight character indicates that the studio still sees potential in the Eternals franchise.
