Rachel McAdams Reveals Real Reason She Declined Mean Girls Reunion With Lindsay Lohan and Cast

Rachel McAdams explained why she didn’t want to appear in Walmart’s advertisement that reunited Lindsay Lohan, Amanda Seyfried, and Lacey Chabert from Mean Girls.

Rachel McAdams didn’t join the Mean Girls cast for their new advertisement.

The Notebook star revealed the reason for her absence from Walmart’s Black Friday ad, which featured a reunion among Lindsay Lohan, Amanda Seyfried, and Lacey Chabert reprising their roles from the 2004 comedy.

So, why did McAdams—who portrayed Plastic queen Regina George—reject the offer?

“I don’t know,” she told Variety in an interview published on December 20. “I guess I wasn’t that excited about doing an ad if I’m being totally honest. A movie sounded awesome, but I’ve never done ads, and it just didn’t feel like my thing.”

McAdams, 45, also admitted that she wasn’t aware it would be such a big gathering.

“I didn’t know everyone was doing it,” she noted. “Of course, I’d always love to be part of a Mean Girls reunion and hang out with my Plastics, but yeah, I found that out later.”

For Lohan, it was a long-awaited moment to reconnect with Seyfried and Chabert, who portrayed Karen and Gretchen on screen.

“It was so nice being back together after all these years,” the Parent Trap actress said in a statement to E! News last month. “It was great catching up with everyone.”

Chabert also shared, “It was wonderful to spend the day with Amanda and Lindsay… It was so much fun to reminisce and be together again after all these years.”

The trio was also joined in the ad by their co-stars, Daniel Franzese, who portrayed Cady’s friend Damian, and Rajiv Surendra, who played the Mathletes captain and emcee Kevin G.

LiLo Didn’t Want to Be Cady…

When Mark Waters—who had directed Lindsay Lohan in Freaky Friday—visited the actress in Toronto while she was filming Confessions of a Teenage Drama Queen, he asked her if she wanted to be in his movie. And she had one role in mind.

“I wanted to play Regina. I had just played—in Confessions and Freaky—not the cool girl in school,” she recalled to Entertainment Weekly in 2014. “I was still 17 years old and I wanted to be the cool girl on set.” But amidst the difficulty in finding a Cady strong enough to face off against her Regina and the massive success of Freaky Friday, it became evident to those in charge that a change was needed.

“Sherry Lansing, who was heading Paramount at the time, told us, ‘We have to have Lindsay play the lead in Mean Girls. It’s just not going to work having her play the villain, because she now has an audience that won’t accept that,'” Waters told Vulture in 2014, revealing it was up to him to deliver the bad news to the actress. “Lindsay kind of begrudgingly said, ‘Okay, I guess I’ll play the lead. At least I get to have more lines.'”

…and Rachel McAdams Did

Before Waters replaced Lohan from the Regina role, he had several actresses come in and read opposite her as Cady. One of them was 24-year-old Rachel McAdams. “I remember watching her do the scene,” Waters told Vulture, “and after it was over, I told her, ‘I think you’re a movie star, but you’re way too old for this character. You just aren’t going to be able to play the ingenue.’ And she said, ‘No, I understand, I get it.'” When it came time to find a new Regina, however, casting McAdams became a no-brainer. As she told EW, “Mark said, ‘I see Cady a little bit younger, but I think it makes sense if Regina kind of grew up a little too fast.'”

An Alternate Regina

Before McAdams could land the Regina role, she had to persuade the director away from another future co-star: Amanda Seyfried. The Mamma Mia! actress was a serious contender for the villainous lead before ultimately becoming the delightfully daft Karen. “She tested for Regina and was kind of brilliant, and very different than Rachel’s approach. She played it in a much more ethereal but still kind of scary way. She was more frightening, but oddly, less intimidating,” Waters recalled, before adding that it was producer Lorne Michaels who suggested her for “the dumb girl.”

He continued, “So she came in and read it and nailed it, and we got the best of both worlds.”

A Fight for Tim and Amy

Although it seems unimaginable to picture Mean Girls without SNL legends Tim Meadows and Amy Poehler in the roles of Mr. Duvall and Mrs. George, Waters openly acknowledged that Paramount was apprehensive. “It’s weird, but Paramount had a nervousness about Saturday Night Live,” he told Vulture. “They’d been burned on some Saturday Night Live movies that had come from Lorne, so they didn’t want many Saturday Night Live actors in Mean Girls, because then it might feel like an SNL movie and people might shy away from it.” Meadows, who had starred in the flop adaptation of The Ladies Man for Paramount, faced “a lot of fighting with the studio,” Waters added.
