TV host and comedian Harry Hill chats to fellow comedian and actor Tim Vine in the talk tag show. From March 2017.

Harry Hill turns interviewer and invites his chosen guest Tim Vine into the Chain Reaction hot seat.

Chain Reaction is the talk show with a twist where one week's interviewee becomes the next week's interviewer. John Cleese was first in the hot seat back in 1991 and since then, a procession of big names from the world of comedy and entertainment including Jennifer Saunders, Jarvis Cocker and Eddie Izzard have helped continue the chain.

Harry Hill is an award-winning comedian and world-class swingball player. Born in Woking in 1964, he holds a medical degree from the University of London. His books include Flight from Deathrow and Tim the Tiny Horse. He has been a stand-up since the early 90s and is well known as the star of TV Burp and the voice of You've Been Framed. Harry can currently be seen on Alien Fun Capsule.

Harry is joined by Tim Vine (AKA The Punslinger, The Joke-a-motive or The Punaway Train). Tim is best known for his frenetic stage shows, rammed full of rapid one-liners, songs and props. He previously starred in BBC1s Not Going Out, ITV1’s The Sketch Show and hosted the seminal Channel 5 quiz show Whittle.

Together they discuss Tim's teenage dreams of being a pop star, giant moths and the roots of Tim's act.
