Joining them - at least in voice - is narrator Sophie Willan.

Providing voice over throughout The Circle, she joins Emma Willis on the hosting team with Emma fronting live shows from the studio.
What is The Circle?
In Channel 4's The Circle, contestants live separately confined to single apartments shared only by cameras watching their every move.
In a game where anyone can be anyone, never meeting one another in person, the only way contestants can communicate with each other is through voice-activated social network The Circle.
Contestants rate each other frequently and unpopular players are blocked.
Ultimately, the most popular player at the end of the series stands to win a cash prize of up to £100,000.
The Circle airs Monday-Friday and Sunday nights on Channel 4.
If you're not near a TV, you can watch episodes live as they air via the All4 Channel 4 Live Player.
