It Started, Now It's Finished - S25.E14

Last week's Mastermind final marked the end of the quiz which became a national institution during its 25-year run. This documentary follows the last four contenders to sit in the black chair as they prepare for the "final final", and explores the programme's appeal.

Featuring interviews with Patrick Moore, Bamber Gascoigne, former winners, and question master Magnus Magnusson.
