Tonight, this week's movie special reaches its thrilling climax. The show starts with a blockbuster group routine from our stellar cast before the remaining 14 Strictly stars find out who must face the drama of the Dance Off. There's also music from Harry Connick Jr, who will be performing Anything Goes.
The show pairs a number of celebrities with professional ballroom dancers who each week compete against each other to impress a panel of judges and the viewing public in order to survive potential elimination. Through telephone voting, viewers vote for whom they would like to stay, the results of the poll being combined with the ranking of the panel of judges.
The show is broadcast live on BBC One on Saturday evenings, and is presented by Bruce Forsyth and Tess Daly. The judging panel consists mainly of Bruno Tonioli, Len Goodman and Craig Revel Horwood.
