VIDEO: What Caused a Giant 'Weepfest' When Mandy Patinkin Visited 'SUNDAY IN THE PARK'?

On today's LIVE WITH KELLY, guest Mandy Patinkin talked about the emotional experience he had seeing Jake Gyllenhaal in the Sondheim musical Sunday in the Park with George, now on Broadway. "As the piece began, I just started to weep. And then I was very concerned I would be too loud in the audience crying," shares the actor who originated the role of painter Georges Seurat. After greeting Gyllenhaal and co-star Annaleigh Ashford backstage, Patinkin reveals, "we wept for many minutes!" Watch the appearance below!

Sunday in the Park with George is now running at the historic Hudson Theatre on Broadway for a strictly limited 10-week engagement. Directed by Sarna Lapine, the show began performances on February 11 and officially opened on February 23rd, and will play through Sunday, April 23rd.

Academy Award nominee Jake Gyllenhaal (in his Broadway musical debut) and Tony Award winner Annaleigh Ashford will be joined by Tony Award nominee Brooks Ashmanskas, Jenni Barber, Tony Award nominee Phillip Boykin, Mattea Marie Conforti, Erin Davie, Claybourne Elder, Tony Award nominee Penny Fuller, Jordan Gelber, Tony Award winner Robert Sean Leonard, Liz McCartney, Tony Award winner Ruthie Ann Miles, Ashley Park, Jennifer Sanchez, David Turner, Max Chernin, MaryAnn Hu, Tony Award nominee Michael McElroy, Jaime Rosenstein, Julie Foldesi, and Andrew Kober.

Sondheim and Lapine's masterpiece follows painter Georges Seurat (Jake Gyllenhaal) in the months leading up to the completion of his most famous painting, A Sunday Afternoon on the Island of La Grande Jatte. Consumed by his need to "finish the hat," Seurat alienates the French bourgeoisie, spurns his fellow artists, and neglects his lover Dot (Annaleigh Ashford), not realizing that his actions will reverberate over the next 100 years.
