Niall has been working in theatre and comedy ever since he left Lancaster University with a BA (Hons) tucked under his slender arm. (The arm's a bit bigger now).
Via the skilful art of following his hunches, Niall has worked in myriad fields and disciplines. One week he is co-devising a new theatre project; the next he is running a business workshop in the art of improvisation. The evening might see him performing with the world's only improvising opera company, the jaw-dropping Impropera, or guesting with the brilliant Comedy Store Players.
He has numerous television appearances behind him (including Whose Line Is It Anyway and Outnumbered) and has written and performed solo shows for the stage and for radio. He's the father of two beautiful and tiring children, and a supporter of Everton football club. But that needn't stop you from talking to him.
So who does he think he is?
He's whoever it is he's being that day.
