In a statement, the 82-year-old Funny Girl star revealed more details about the project.

"For years I've been thinking about the best way to share the vast amount of content I've been safely storing in my vault," she said. "These films, photos and music masters - many never seen or heard by the public - hold some of my most cherished memories."

"I'm so pleased that producer Alex Gibney and director Frank Marshall have agreed to take this journey with me," Streisand continued. "My appreciation to Tom Mackay, head of Sony Music's Premium Content team, for his belief in the project.
