The Underdog: Josh Must Win — release date, cast, celebrities and everything we know

The Underdog: Josh Must Win is a brand-new spin on the usual reality TV format. 

This fresh E4 series is flipping the script on reality TV mainstays like Love Island and Big Brother. The Underdog: Josh Must Win invites a larger-than-life cast to take part in a new popularity contest called The Favourite. 

Our confident castmates all think they're competing to be crowned the most popular of the bunch, in the hopes of bagging a cash prize at the end. What the group doesn't know is that four celebrities are pulling the strings behind the scenes, doing everything in their power to make the underdog of the group come out on top.

Here's everything you need to know about The Underdog: Josh Must Win... 

The Underdog: Josh Must Win release date

The Underdog: Josh Must Win starts airing on E4 on Monday, March 25 at 9 pm, with new episodes airing Monday - Wednesday in the same slot. 

You'll be able to stream the series on Channel 4, too; the first three episodes will be available to stream immediately after the first one airs. 

How does The Underdog: Josh Must Win work?

The Underdog: Josh Must Win sees a group of would-be reality stars heading to a luxury home, where they think they're taking part in a popularity contest TV show called The Favourite, hosted by Nick Grimshaw.

Secretly, our four celebrity panelists will be hidden away in a nearby room. From their observation room, the group will keep a close eye on the proceedings and do their best to control the group and ensure that Josh comes out on top. 

They'll be doing what they can to manipulate the game, assigning tasks and revealing surprise format changes, using their own experiences of reality TV to try and guarantee Josh's win... all while trying to keep up the facade of the fake show and not being found out!
