Witherspoon measures up as Carter in 'Walk the Line'

Reese Witherspoon got quite a shock when she met the children of late country legend June Carter, the woman she portrays in “Walk the Line.” “I was told that my boobs weren’t big enough,” she says with a laugh.

There was another big surprise. “I didn’t know I was singing when I signed on for the movie,” she says. “I was fine doing the acting bit, but I didn’t realize about all the singing. So Joaquin and I went into it with a lot of trepidation, especially as he was playing an icon that had such a recognizable, memorable voice.”

It turns out that she had a little stage fright the first time she had to sing in the movie. “Two people literally had to push me onto the stage, saying, ‘You have to do it! We’re all waiting for you!’ ” she reports. “And I thought I was going to throw up the entire first day, it was awful.”

Witherspoon says she could relate to the way Carter handled fame and success in the public eye.

“She did all these things in the 1950s when it wasn’t acceptable for a woman to be married and divorced twice and have two different children with two different husbands and travel around in a car with all these famous musicians all by herself,” Witherspoon explains. “She didn’t try to comply with social convention.”
