The Chase Christmas special 2017 airs tonight on ITV but who's on the show and when does it start?
Tonight's Christmas special of The Chase sees the Chasers get in the festive spirit by dressing up as characters from Charles Dickens' A Christmas Carol.
Mark Labbett (The Beast) dons a Tiny Tim costume, while Jenny Ryan (The Vixen) takes on Mrs. Cratchit.
Paul Sinha (The Sinnerman) becomes Ebenezer Scrooge, with Shaun Wallace (The Dark Destroyer) as Jacob Marley.
Meanwhile, Anne Hegerty (The Governess) tries her best to spook us as the Ghost of Christmas Past.
Bradley also gets in on the act, appearing as Charles Dickens himself.
For one night only, a team of celebrities takes on all five Chasers to win thousands of pounds for charity.
Entertainer Jimmy Osmond, Coronation Street actor Patti Clare, comedian Matt Richardson and Newsnight anchor Kirsty Wark are the famous faces taking part.
"Pull up a chair and roast some chestnuts as Bradley Walsh hosts a special edition of The Chase," said ITV.
A Christmas Chase: Celebrity Special airs tonight on Sunday 24th December at 5.50pm.
It's the second of two one-off specials for the festive period, following a one-off clip show.
'The Chase: The Bloopers' aired last week and revisited some of the most hilarious footage from throughout its eight-year history.
Presenter Bradley Walsh introduced classic blunders and slip-ups, as well as never-before-seen outtakes.
You can catch up with the specials online via the ITV Player.
