Red Nose Day Live, which raises money to combat child poverty, is taking a multiplatform approach for this year's installment. It all starts at 5:30 p.m. ET with a pass-the-baton-style approach, moving across creator channels and streams. But the easiest way to view it is on Red Nose Day's YouTube channel or at RedNoseDay.Org/Live, powered by fundraising platform Tiltify.

Among the talent already announced are a mix of gamers and celebs, including Jennifer Garner, Tony Hale, Never Have I Ever's Maitreyi Ramakrishnan, Joel McHale, Lamorne Morris, Game Theorists' MatPat, Rooster Teeth, Neekolul, and Crank Gameplays' Ethan Nestor.

Red Nose Day programming will also return to NBC that evening (at 8 p.m. ET/PT), featuring a fast-paced themed episode of game show The Wall, being played by a Houston family described by the network as "community-focused." Additionally, host Chris Hardwick will have an opportunity to raise funds for the cause as he tries out the wall himself. The network promises surprise celebrity guests will appear in the episode.
