The actress is giving all of us a reminder today, though, care of the fire-y red hair color she was seen with on set The Undoing, an upcoming HBO miniseries based on the novel You Should Have Known by Jean Hanff Korelitz. Kidman's dramatic color change wasn't the only #TBT aspect of her character Grace Sachs's beauty look. The actress' red hair was significantly more curly than how she's worn it in recent years, and is reminiscent of her natural hair texture.

"I really wanted to have that suntanned skin and long blonde hair," she said. "I wanted to conform and be the Aussie beach girl. And I was never going to be that."

"I wish I had my curls back," she told the publication. "I tortured them to death. I always say, 'Don't ruin the ringlets!'"
