Catherine Tate interviews David Tennant

Available for over a year

It's a meeting to two Doctor Who stalwarts. Catherine Tate takes the host's chair as she talks to - or mercilessly teases - David Tennant. Chain Reaction is the tag talk show with a twist where the guest becomes the interviewer in the next show. Based on the original 1991 BBC Radio 5 programme of the same name, Chain Reaction is a simple idea of big name stars from the world of entertainment interviewing others whose work they appreciate and admire. Recorded with an audience, the interviews focus on the life, career and the passions of the interviewee but often prove to be as revealing about the interviewer. Producer: Tilusha Ghelani. First broadcast on BBC Radio 4 in February 2008.
