Legally Blonde, which casts Witherspoon as Harvard Law student Elle Woods as she defies expectations to excel in the courtroom, was followed up with a sequel in 2003, subtitled Red, White & Blonde. Mindy Kaling is currently drafting a third installment.

The 41-year-actress told Good Morning America earlier this month that she spent years quoting the iconic movie to her friend and frequent costar Witherspoon, before Witherspoon approached her with the idea to make a third movie.

“I'd been working with her on a couple movies and we've been friends for a while,” Kaling said. “I have always quoted the movies to her — I was that annoying friend that would be like, ‘Bend and snap' to her. And she asked me, ‘You know, I'd really love to revisit this character.'”

Her first reaction was apprehension, she said. “I was nervous because the movie is so iconic,” recalled Kaling. “But then I thought, ‘It'd be really fun to see that character in her 40s. What is Elle Woods dealing with as a 41-year-old woman?'”

Kaling, who confirmed her involvement with Legally Blonde 3 in May, continued: “It's been really funny to write. I'm working on it with my friend Dan [Goor], and I think it's going to be a great movie for Reese and people are going to love to see her in this part.”

Legally Blonde 3 was first announced back in June 2018. "We’re definitely talking about it," Witherspoon had said at the time. "I mean, it’s sort of about women being underestimated and I think it’s sort of a good idea. Things have changed, but not that much has changed! I loved playing that character and she’s so amazing."
