All the people wearing red noses on NBC Thursday night will not be clowns.

They will in fact, be mirroring a charitable UK occasion, called Red Nose Day, that is an organization run by the non-profit, Comic Relief Inc. The annual event has collected over $1 billion for impoverished children in its 30-year history.

This year, it was the launch site for the highly anticipated “Love, Actually” short sequel, “Red Nose Day, Actually.”

The edition taking place Thursday night on NBC has relied on proven fundraising methods from its British counterpart: Red Nose Day contributors buy red foam noses, organize events and donate money during the show.

What’s Red Nose Day and what’s it got to do with ‘Love Actually?’.

“We’re taking the best practices in the UK – incredible partnerships, including our broadcast partner, NBC, and Walgreens – to fashion Red Nose Day here,” CEO of Comic Relief Janet Scardino told The Drum.

The night kicks off with a celebrity edition of “American Ninja Warrior,” the first time celebs will face the famous obstacle course and all for charity.

Julia Roberts joins Bear Grylls for a special “Running Wild with Bear Grylls for Red Nose Day” in Kenya to deliver vaccines.

“We are thrilled to have Chris’ wit and compassion championing the evening as our host for ‘The Red Nose Day Special.'”.
