Behind The Sofa is a collection of over 100 celebrity memories of Doctor Who, compiled in aid of Alzheimer's Research UK. Steve Berry decided to undertake this project in memory of his mother Janet, who suffered from Alzheimer's in her final years and passed away in 2009. Contributors include comedians Al Murray, Stephen Merchant, and Bill Oddie; actors Lynda Bellingham, Nicholas Parsons, and Rhys Thomas; writers Neil Gaiman, Jenny Colgan, Jonathan Ross, and Charlie Brooker; and politicians Louise Mensch and Tom Harris. In addition, there is input from a number of the writers, actors, and production staff who were involved in creating Doctor Who stories new and old.
