Two Halloween powerhouses are joining forces this season to create a one-of-a-kind, interactive Halloween experience, It’s A LIVE – a ‘trick’ or ‘treat’ house of epic magnitude. 

Halloween fanatic Neil Patrick Harris will supply the tricks and Reese’s Peanut Butter Cups will provide the treats.

There are two ways to participate in this unique house full of scary tricks and sweet treats. Starting Oct. 1, fans can vote to help determine what tricks and treats will go into It’s A LIVE. And then, fans can also come back on Oct. 24 and choose exactly which path each guest experiences, in real time!

Here’s how it works. Throughout the month of October, fans following Neil Patrick Harris on Instagram and Facebook will have the opportunity to co-create both the scariest and sweetest Halloween house. Clowns or snakes? Edible chocolate wallpaper or a tub of Reese’s peanut butter? Fans pick the tricks and fans pick the treats. 

Then on the night of Oct. 24, a few lucky fans will experience the first-ever, crowd-sourced trick-or-treat house, full of scares and an over-the-top treat experience that puts any candy land to shame. But the best part? It’s going to be on Facebook LIVE for all of America to see, and viewers will get to choose the fate of the 32 specially selected participants. Viewers will vote via a Facebook Live poll to dictate the path of those making their way through It’s A LIVE.

“Halloween has always been my favorite – elaborate costumes, epic decorations and the ability to scare people,” Harris said. “So to have the Reese’s brand (and anyone watching live) help provide the most epic, larger-than-life Halloween experience? Well, it‘s simply terrifying – in the greatest way imaginable.”

The It's A LIVE concept originated from a team of scary geniuses, led by Neil Patrick Harris and the Reese’s brand, with help from Matador Content and Facebook Creative Shop. 

“We are the undisputed leaders of Halloween. Last year we allowed people to trade their trick-or-treat candy for Reese’s Peanut Butter Cups. This year, we had to up our game and provide the most epic Reese’s Halloween treat experience to date,” said Eric Bowers, senior manager, Halloween, for the Reese’s brand.
