Kumail Nanjiani has been busy with work ever since he starred in Chloe Zhao's MCU movie Eternals, but he's still excited about the possibility of coming back to the MCU if the Eternals sequel gets the green light.

Nanjiani expressed his desire to portray Kingo once more in a recent interview with Total Film, saying:
Yeah! I mean, listen, I have plans today. I don’t know if they have plans. I would love to come back. But I’m sort of waiting to hear when or if that’s going to happen. I’m hoping I get to do more. I had a great time playing that character. It’d be a shame if he’s a sort of one-and-done. But, you know, the decision’s not mine to make.
Marvel Studios hasn't officially announced a sequel for Eternals, despite the fact that his character was the subject of multiple Easter eggs on the most recent Guardians Of The Galaxy Holiday Special. It's quite likely that Nanjiani's return as Kingo won't be in an Eternals sequel since Eternals was not well received by critics and audiences.
For a while now, MCU films have been on the receiving end of constant criticism, especially from the American directors, Quentin Tarantino and Martin Scorsese. In 2019, Scorsese's controversial remarks about Marvel films evoked anger among many Marvel fans after he said:
I don’t see [Marvel movies]. I tried, you know? But that’s not cinema. Honestly, the closest I can think of them, as well-made as they are, with actors doing the best they can under the circumstances, is theme parks. It isn’t the cinema of human beings trying to convey emotional, psychological experiences to another human being.
Even though he disagreed with Scorsese's assessment of the films, Nanjiani defended his right to criticize them.
I obviously love the movies Tarantino makes or Scorsese makes, and I may disagree with Scorsese’s opinion on superhero movies, but I mean, who else has earned the right to have an opinion?
If Scorsese hasn’t earned the right to have an opinion on movies, then none of us should have an opinion on movies. It’s so strange that people get upset about it.
In 2017, Nanjiani was nominated for the Academy Award for Best Original Screenplay for the romantic comedy film The Big Sick, and since then, he has gone on to star in big Hollywood productions such as Men in Black: International, The Boys, Obi-Wan Kenobi, and Hulu's biographical drama miniseries, Welcome to Chippendales.
Eternals 2 will be Judgment Day and be more cosmic. Chloé Zhao is not attached and there's a chance she will not return to do the sequel
