Matt Lucas and Noel Fielding present a festive special doubling up as a celebration of Channel 4's 40th anniversary, with five contestants from the channel's history. Gaby Roslin (The Big Breakfast), Tony Robinson (Time Team), Miquita Oliver (Popworld), Terry Christian (The Word) and Claire Sweeney (Brookside) are the Channel 4 veteran competing for the title of Christmas Star Baker, and hoping for a Hollywood handshake along the way. As a special treat, the show ends with a performance by the English National Ballet
