Who says blondes have more fun? Filming The Good Lie in Atlanta on Thursday April 11, a nearly unrecognizable Reese Witherspoon was made over into something of a sexy-casual Southern girl, complete with turquoise top, denim skirt, cowboy boots -- and long, flowing brown hair. The 37-year-old Oscar winner first debuted the dark 'do earlier this month in Nashville, arriving there with son Tennessee, 6 months, and hubby Jim Toth.

In The Good Lie, Witherspoon plays a woman who befriends refugees during the Sudanese civil war. Fans have seen the blonde, blue-eyed actress go brunette before to award-winning effect: To play June Carter Cash in the Johnny Cash 2004 biopic Walk the Line, Witherspoon similarly dyed her signature locks.

"It's great to be brunette," Witherspoon said at the time. "Nobody knows who I am. Everybody walks right past me. It's a nice reprieve from my normal self." The mother of three won an Academy Award for Best Actress in the role as well.
