The film tells the story of Joe Gardner, a middle school band teacher voiced by Jamie Foxx.
"Like a lot of us, he's living day to day and thinking that if he could just achieve this one thing he really wants to do, then his life will really start," co-star Tina Fey told our sister station 6abc in Philadelphia. "But his life has been happening this whole time."
Fey plays 22, a soul who has never been born and wants to keep it that way.
"With this story, we are able to explore the idea of personality and spirit and purpose in life," Fey says.

Ahmir 'Questlove' Thompson plays Curly, one of Joe Gardner's former students who gives him his big break.
"Joe Gardner is a person who had a spark and had a flame and somehow his passion turned into a job," Questlove said. "Add to that that it's happening in 2020, when a lot of us are going through the same thing -- it couldn't have come at a better time."
Questlove also helped creators choose the film's background music.
"They told me who the characters were and I asked every question under the sun about that character, and I figured out what they would listen to," he said, thrilled to have this task in the film.

But it's 22 who helps Joe reconnect with his soul.
"People should watch 'Soul' on Christmas Day because it's a perfect movie to remind how lucky we are to be alive," Fey says.
"Soul" will be available to stream Christmas Day exclusively on Disney+.
