Hitting prime time, presenter Rachel Riley, Emmerdale star Mark Charnock, ex-politician Edwina Currie and Boyzone singer Keith Duffy are quaking in their boots as they face the might of The Chaser.
Taking on one of the biggest quiz brains in Britain is a scary prospect anyway, but doing it on television might just stop these stars from sparkling. Who'll be the cleverest celeb on show?
We expect Edwina to be pretty intelligent and Rachel Riley does present Countdown, so she's certainly got a brain in her head, but this is general knowledge – if they don't know their Spice Girls from their spices, could they end up out of The Chase?
The Chase, ITV1, 7pm
