Celebrities are set to become time travellers in a new Channel 4 game show, Time Crashers.
The week-long show will feature a group of celebrities being thrown into different time periods without the aid of modern technology.
Each episode will include eight stars 'crashing' somewhere in the UK in different eras from the past, where they will be fully immersed in the period.
The celebrities will have to work together in different challenges, before one becomes the ultimate Time Crasher at the end of the week.
Justin Gorman, Head of Entertainment for Channel 4, said: "With Time Crashers, we've commissioned a highly innovative fusion of entertainment and British history that will appeal to a broad TV audience."
It is expected to begin filming in March 2015, and will be broadcast later in the year.
