Charlie Higson says: "It's great to be back with this Down The Line one-off special. A spoof radio phone-in show is the perfect project to make in lockdown as all the cast can literally phone their performances in. So we have a great range of characters calling our host, Gary Bellamy, who are as weird, confused, angry and nuts as the callers on any other phone in show. The only sadness is that this is the first Down The Line we've made without the inimitable Felix Dexter, whose unique characters were such a big part of the show. Otherwise, all of the original cast - Rhys Thomas, Paul Whitehouse, Lucy Montgomery, Simon Day, Charlie Higson, and Amelia Bullmore are back, as well as guest stars including Harry Enfield, Robert Popper and Geoff Schumann."
