Mark Rober, Jimmy Kimmel Join Forces For Star-Studded Stream To Support The Autism Community

A prank-themed television series for the Discovery Channel isn’t the only project that Jimmy Kimmel and YouTube engineer Mark Rober have in the works.

The duo are teaming on a three-hour live stream to raise money for Next For Autism — an organization that works to address the needs of people with autism and their families through educational, clinical, and vocational programs nationwide. This is a cause close to Rober’s heart, given that he has an autistic son, he shared in a YouTube video today (below) that also served as an announcement for the blockbuster fundraising stream.

The YouTube Originals event will take place right here on April 30 at 8 pm ET on Rober’s channel, which is home to 17.9 million subscribers and 80 million monthly viewers. The event will comprise musical performances, comedy skits, DIY science stunts, viewer interaction, and more.

Officially titled Color The Spectrum, the star-studded lineup includes: Adam Sandler, Andy Samberg

, Chris Rock, Conan O’Brien, John Oliver, Jack Black, Jon Stewart, Mark Hamill, Marques Brownlee, Maya Rudolph, MrBeast, Paul Rudd, Rhett & Link, Sarah Silverman, Stephen Colbert, Terry Crews, and Zach Galifianakis.

The fundraising is being powered by creator-centric platform Tiltify, and produced by Michelle and Robert Smigel, whose Jon Stewart-fronted Night Of Too Many Stars benefits inspired Rober to create his own event. The Smigels also have an autistic son named Daniel.

“Autism awareness is such a personal cause for my family and me,” Rober said in a statement. “It is inspiring to team up with Jimmy and Robert and create this unprecedented opportunity to bring together traditional entertainment stars with some of the world’s biggest YouTube creators. I don’t think we have ever seen these worlds unite on a scale like this before. The best part is that this is all being done for people in need and who are so deserving.”
