Neil Patrick Harris is returning to the small screen in a major way as the host of Netflix’s upcoming game show What’s in the Box, set to premiere in December 2025.

The new series is described by Netflix as a “massive guessing game” filled with suspense, twists, and the potential for life-changing rewards.
The format centers around giant mystery boxes that conceal high-stakes prizes.
Pairs of contestants will battle through fast-paced trivia rounds before attempting to guess what lies inside each box.
According to Netflix, the stakes go far beyond just winning a prize.
“Winning a prize is just the beginning,” the streamer says, teasing dramatic twists, shifting alliances, and a format that rewards sharp instincts and a little bit of luck.
Only those with keen decision-making skills will walk away victorious.
Netflix has ordered six 45-minute episodes of What’s in the Box, produced by Rollercoaster Television, which is part of ITV Studios.
The series is executive produced by James Fox, Dom Waugh, Wes Kauble, and Leanne Witcoop.
