Principal photography is to begin in March with Lionsgate to release the film in the United States.
"We are absolutely thrilled to have such a talented superstar as Harrison Ford join this project and can't wait for production to get underway," Lionsgate Motion Picture Group Co-Chairs Rob Friedman and Patrick Wachsberger said in a joint statement.
The original screenplay was written by J. Mills Goodloe and Salvador Paskowitz, with revisions made by Allison Burnett. The picture is being directed by Lee Toland Krieger.
The movie is about a 29-year-old woman who stops aging after recovering from a near-fatal accident.
