Newstalk presents a new Documentary produced by Michael Cullen, that introduces us to some of Ireland's most successful quizzers. "Know It All" looks at the quizzing scene in Ireland, and talks to some of its most successful participants, including two winners of Mastermind, and a winner of the million on Who Wants To Be A Millionaire.

"Know It All" will air on Sunday August 27th at 7am, repeated Saturday September 2nd at 9pm, and will be available as a podcast.

Ireland has produced some of the world’s most successful quizzers. These include Dave McBryan, Mastermind champion and winner of the final of Fifteen to One; Mark Henry, European champion; and Pat Gibson, Egghead panellist, Mastermind Champion of Champions, and winner of one million pounds on Who Wants to Be A Millionaire.

In “Know It All” they relive the excitement of those victories, and reveal some of their quizzing secrets. We go inside the Irish quizzing scene, and talk to rising stars Patrick Carthy and Eva Barrett, as they prepare for the 2023 World Championships.

There are also questions to try out yourself, and memory tips, which can be useful both in quizzing and in everyday life.  

“Know It All” was produced by Michael Cullen, and was supported by a grant from Coimisiún na Meán, as part of the Sound and Vision Scheme.
