“You couldn’t have made this movie three years ago,” said Robert Zemeckis, the director of “Here.”

The film stars Tom Hanks and Robin Wright, and is based on a 2014 graphic novel that takes place in a single spot in the world over several centuries. The story mostly takes place in a suburban New Jersey living room. It skips back and forth through time, but focuses on a baby-boomer couple — played by Hanks and Wright — at various stages of their lives, from age 18 into their 80s.

Before A.I. software, Zemeckis could have had multiple actors play each character, but the audience might have gotten lost trying to keep track. Conventional makeup could have taken a decade off Hanks, who is now 68, but not half a century. The issue with C.G.I. is time and money. Persuading us that we’re watching Hanks and Wright in their 20s would have required hundreds of visual effects artists, tens of millions of dollars and months of postproduction work. A.I. software, though, changed all that accounting.
