I Literally Just Told You: Celebrity Christmas Special | Preview (Channel 4)

Jimmy Carr presents a brand-new festive celebrity special of the gameshow with a unique twist.

To win up to £25,000 for their chosen charities, Dermot O'Leary, Judi Love, David Walliams and Kerry Katona must answer questions that have been written live as the show is being filmed.

These questions can be about absolutely anything that happens during the show, from a celebrity cameo to a comment from resident factologist Dr Maggie Aderin-Pocock - or even a Christmas joke from Jimmy himself!

The stars must use their general knowledge skills to bank cash before relying on their powers of recall to beat their opponents in the memory rounds. In the nerve-racking final showdown, the two players left standing go head-to-head answering questions they have chosen for their opponents about what's just happened in the show.

Whoever can remember the most wins the jackpot. Airs Christmas Eve on Channel 4.
