Actress Reese Witherspoon has signed on to portray late singer Peggy Lee in an untitled biopic, reports Variety. Witherspoon will star in the film as Lee and will also produce the film as well.

Nora Ephron is writing and directing the film for Fox 2000, which also produced the biopic Walk the Line, which Witherspoon starred in alongside Joaquin Phoenix. Witherspoon will produce alongside her Legally Blonde producer Marc Platt.

This new film will revolve around the personal and professional life of Peggy Lee, a singer/songwriter/composer/actress whose career spanned nearly seven decades and is regarded as one of the most influential jazz artists of all time.
