Principal production began on Feb. 27, 2018 in Georgia. Several scenes were also shot in Cartagena, Colombia and Budapest, Hungary. But the movie's real draw is the digital creation technology that allows Will to battle his 23-year-old self.

"The level of the work is so spectacular it’s hard to get people to understand," the Oscar nominee said at a recent press preview. "The special effects people at [Peter Jackson’s VFX house] Weta have done something that has really never been done before."

Director Ang Lee added, "This movie is a leap of faith. The story has been around 20, 25 years, but technology wouldn’t allow the story to be told. I wanted to be the first one to do this…"

Will joked that this advancement in CGI allows him to become a lazier actor. "What I’m excited about is now there’s a completely digital 23-year-old version of myself that I can make movies with now," he teased. "I was like, 'Oh man, I’m going butt and gut on them.' I’m gonna get really fat and really overweight… use the Gemini Junior.

"I’m looking for the movie that is only a digital version of myself," he continued. "Will you be able to make a romantic comedy? Something that has no technology, science fiction elements at all. Will it be that great? I think one day it certainly will."

The Aladdin star explained that Junior is 100 percent digital. "They didn’t take my image and just stretch some of the lines," he shared. "It is a completely CGI character in the same way that the lions in The Lion King are CGI characters."
