Amanda Seyfried says she learned to perform Joni Mitchell’s 1971 album “Blue” in full as part of preparation for a Joni Mitchell biopic that has since been shelved. According to reports, her training included playing songs from the album across multiple instruments. Sources describe Seyfried working to master the material on guitar, dulcimer, and piano while getting ready for the role. The accounts frame the effort as part of an acting and music-prep process tied to the planned portrayal of Mitchell, rather than a new concert or release. Seyfried has also characterized the experience as making her feel like a real musician, reflecting the extent of the preparation. The coverage does not describe a final production release or public performance of the project, and it emphasizes that the biopic is no longer moving forward. Overall, the information centers on Seyfried’s detailed rehearsal for “Blue” and the earlier attempt to adapt Mitchell’s life and music for film.
