Taylor Swift to play Joni Mitchell on big screen Taylor Swift will star as Canadian singer Joni Mitchell in a new movie called Girls Like Us. Variety has confiemed that the 22-year-old country singer will play Mitchell in a film adaptation of Sheila Weller's 2008 book Girls Like Us, which chronicles the lives of Mitchell (below, in 1988), Carole King and Carly Simon and how they reshaped American music. The roles of King and Simon have not yet been cast, although Mad Men's Jessica Pare will reportedly read for Simon's role. Country singer Swift has previously played a small part in the hit romantic comedy, Valentine's Day, alongside ex-boyfriend Taylor Lautner and she also voiced a character in Dr. Seuss' The Lorax. Mitchell, who is now 68, was one of the most popular folk singers of the 1960s and wrote songs such as Big Yellow Taxi and Woodstock, which helped define an era.
