'It' Kids Cast Chris Pratt, Jessica Chastain and More in Dream Sequel (Exclusive)

Stars from director Andy Muschietti’s adaptation reveal to ET who they'd like to see play their adult counterparts.

The kids from It have some pretty genius ideas about which actors should be cast in the sequel.

ET caught up with some of the stars of director Andy Muschietti’s remake of the 1990 miniseries at a press junket for the movie's home entertainment release in Los Angeles on Thursday, where they revealed which celebrities they'd love to see portray their adult counterparts in It: Chapter 2.

Jeremy Ray Taylor, who plays the beloved Ben, says it would be awesome to see a certain Avengers star in the sequel, which will focus on the Losers' Club reuniting 30 years after their first encounter with Pennywise (Bill Skarsgård). Needless to say, we think it's perfect!

"Probably Chris Pratt," he exclaimed.

Seeing as his costar, Wyatt Oleff, worked alongside Pratt as young Peter Quill in the Guardians of the Galaxy franchise, this dream casting isn't too far fetched.

"He becomes a big, hunky boy, so I think that'd fit perfectly," Oleff said of the idea.

As for Oleff, he tells ET he'd love to see an actor that made a recent cameo in Star Wars: The Last Jedi play the grown-up version of Stanley.

"I would say Joseph Gordon-Levitt," he shared. "I think we have some similar facial features and I think if they -- I mean, I don't know what I'm going to look like when I'm older, but if they kind of tighten up the curls, I think [it could work]."

Like Oleff, Sophia Lillis also is basing her dream casting for Beverly on looks.

"Jessica Chastain!" the New York City native, who has strawberry blonde locks, just like the Miss Sloane star, shared.

And Jaeden Lieberher has high hopes for who he thinks should take on the adult version of Bill.

"Christian Bale, maybe?" he revealed. "That would be cool."

When it came time for Jackson Robert Scott to reveal his idea for "grown-up" Georgie, we couldn't help ourselves from laughing over his hilarious, very accurate response.

"Umm, I don't think an adult version of me is going to come back…," he joked, referring to his character's heartbreaking death.

Sorry, Georgie!

The sequel is currently in the works, but when ET asked the kids to spill on what's happening, they all played coy. "I think we'll all find out soon," Lieberher teased. "When the public finds out, we'll find out, too."

No word yet on whether the kids will return in the second film, but they did share some ideas of how Muschietti could make that happen.

"Flashbacks," Lillis suggested. "We were thinking about that, but I think that's it."

Unfortunately, it will be awhile before fans get to see part two of It. Warner Bros. and New Line Cinema announced earlier this year that the movie won't hit theaters until September 2019.

In the meantime, the It kids have their fingers crossed that their adaptation will win big at the 2018 Critics’ Choice Awards in January. It is nominated for Best Sci-Fi/Horror Movie, up against Blade Runner 2049, Get Out and The Shape of Water.

"I'm completely blown away," Oleff said, "just with how far we've come as a group."

"It's very surreal, it's crazy," Ray Taylor added. "I'm a farm boy from Tennessee. Yesterday I was just working on the farm running cattle and stuff, and now in L.A. doing interviews."

So, how does the cast plan to celebrate if It does win? "We celebrate all the time together," Ray Taylor said. "Just because, every time we're together, it feels like a celebration because [we're] always so happy."

It arrives onto 4K Ultra HD Blu-Ray combo Pack, Blu-Ray Combo Pack, DVD from Warner Bros. Home Entertainment on Jan. 9, 2018. Own it early on digital on Dec.19!
