Lisa Jakub, Matthew Lawrence, and Mara Wilson joined Brosnan for an interview with "Today" that will air next month reflecting on the 1993 movie.
“So this just happened. #mrsdoubtfire #reunion #25yearslater,” Jakub tweeted.
Brosnan shared the group photo as well, acknowledging the tragic passing of Robin Williams.
"Guess who? Today, after 25 years, I gathered around a table in the company of three beautiful young people, to talk story about a film that has touched the hearts of so many," Brosnan wrote. "Sally is on tour with her new book. Robin is in heaven making the angels laugh and was spoken of with the fondest of love and and sweet memories."
Brosnan also shared a video from behind-the-scenes of their "Mrs. Doubtfire" reunion.
