Reese Witherspoon has played both the vindictive girl you love to hate and the sweet blonde next door, but we saw a new side of her talent in 2005’s “Walk the Line.” Having never sung professionally before, Witherspoon was so terrified of recording vocals and performing in front of a live audience for her role as June Carter Cash that she almost backed out of the film. But her determination and passion won her an Oscar, Golden Globe, BAFTA, and Screen Actors Award.
