On Saturday, the Big Little Lies star took to Instagram to share a series of clips from her 2002 romantic comedy Sweet Home Alabama.

In the film, Witherspoon plays Melanie, a New York City fashion designer who returns to her small hometown in the South in order to get a divorce from his first husband, played by Josh Lucas.

The film also stars Melanie Lynskey as her former best friend and Patrick Dempsey as the current fiance waiting for her back in Manhattan

Dakota Fanning, in one of her earliest roles, portrays a young version of Witherspoon’s character.

20 years ago Sweet Home Alabama came out and completely changed my life.

Incredible memories of shooting this movie with these amazing actors —Josh, Patrick, Dakota, Melanie, Jean, Ethan, Mary Kay, Fred, and Candace, of course,” Witherspoon wrote in the caption of her post.

Witherspoon’s followers loved the throwback — including Dakota Fanning’s sister, The Great star Elle Fanning, who wrote “THE BEST.”

"I'm still hoping that Legally Blonde 3 is gonna come together in the right way," the Walk the Line actress told USA Today last year.

It's just like Top Gun: They waited a long time to make another version of that movie, and I loved the nostalgia piece they incorporated in it.
