The first four episodes of the series saw dancers aged 7 and up perform any dance style in The Greatest Dancer studio in their bid to impress the audience.
If 75 per cent of the audience voted, the mirror opened, sending them through to the callbacks.

Our four superstar Dance Captains Todrick Hall, Cheryl, Matthew Morrison and Oti Mabuse had the tough job of whittling down the acts who the mirror opened for and deciding upon their final three to mentor in the Live Challenge Shows.

The live shows will see each of the dancers take on a challenge with their Dance Captain to create an unforgettable performance. The power is in the hands of the viewers at home as they vote to decide who stays in the competition each week and who will become The Greatest Dancer.
