Rachel McAdams Explains Why She Opted Out Of 'Mean Girls' Reunion

However, the actor might have been more receptive to the idea if she had been informed of a key detail beforehand.

Audiences yearning for a “Mean Girls” sequel got their wish granted ― well, sort of ― last month when actors Lacey Chabert, Lindsay Lohan and Amanda Seyfried reprised their roles from the 2004 film for a buzzy Walmart campaign.

Still, it was impossible to ignore the absence of Rachel McAdams, whose queen bee character, Regina George, delivered some of the movie’s most-quotable lines and was its main antagonist.

Speaking to Variety in an interview published Wednesday, McAdams explained why she’d chosen to sit out the reunion.

“I guess I wasn’t that excited about doing a commercial if I’m being totally honest,” she said. “A movie sounded awesome, but I’ve never done commercials, and it just didn’t feel like my bag.”

She went on to note that she wasn’t aware that Chabert, Lohan and Seyfried ― who portrayed fellow “Plastics” Gretchen Weiners, Cady Heron and Karen Smith, respectively ― had signed on before making her decision.
