The cast of Mrs. Doubtfire is bringing on a wave of nostalgia for its fans.

The iconic 1993-released movie featured Robin Williams (Daniel Hillard and the titular character, Mrs. Euphegenia Doubtfire)—who tragically passed away in 2014—along with Sally Field (Miranda Hillard), Pierce Brosnan (Stuart "Stu" Dunmeyer), and more.

The former child stars who portrayed Williams' children in the beloved comedy recently reunited to celebrate the film's 31st anniversary, taking to Instagram to share the photo.

"So funny that the same week I went to San Francisco, I got to reunite with my Doubtfire siblings! It’s always a joy to see @lisa.jakub and @matthewlawrence," Wilson wrote in the caption of the post, also revealing that she was a guest on The Brotherly Love Podcast, which is hosted by Lawrence and his actor brothers Joey and Andy.
