While catching up with ET Canada’s Morgan Hoffman, Bullock opened up about the many real-life female prisoners she met with while researching for the role.

“The more I talked to incredible human beings that were in the prison system, incredible human beings that had been released from the prison system and you heard their stories of the moment they arrived on this planet, they all had similar themes,” she recalled. “It’s resources, it’s poverty, and it’s the lack of eyes on you seeing you as valuable.”

Bullock’s co-star Rob Morgan also revealed how difficult it was to show the Academy Award-winner tough love as her parole officer in the film.
