Meryl Streep is confirmed to portray Joni Mitchell in Cameron Crowe's biopic, as announced by Clive Davis.

The confirmation came during Davis's pre-Grammy party at the Beverly Hilton in Los Angeles, where he introduced Mitchell and disclosed Streep's casting for the project.

The film is set to chart Mitchell's early folk rise and lasting influence, with notes that personal storytelling may draw on Mitchell's preserved costumes and instruments.

Online chatter has floated Amanda Seyfried as a potential younger Mitchell, highlighted by a viral Tonight Show performance clip.

Crowe has described the project as a personal, intimate look at Mitchell's life and music, built around a perspective-focused narrative.

Public discussions about the project have emphasized an ongoing, multi-year development with conversations about its approach and scope.

Representatives for Meryl Streep and Joni Mitchell did not respond to requests for comment at the time.

Anya Taylor-Joy has been widely rumored to portray the younger Joni Mitchell, though no official confirmation has been made.

Crowe’s interest in Mitchell’s personal history is echoed by reports that she retains costumes, instruments, and even her Laurel Canyon house as part of the narrative.

Cameron Crowe has been developing the biopic for about four years, aiming to tell Mitchell's life and music from her own perspective.

Casting speculation has persisted since mid-2024, with Taylor-Joy previously floated for Mitchell's younger years.

Mitchell remains active, performing at the Grammys in 2024 and continuing to appear in live performances, as the biopic develops.
