James McAvoy introduces us to his Neverwhere character Richard Mayhew in this brand new clip from the BBC Radio 4 drama.
Adapted from award-winning author Neil Gaiman’s novel, Neverwhere sees Mayhew catapulted from his ordinary life into a subterranean world beneath London following an act of kindness.
“I helped a girl called Door, now something strange has happened and it's like I'm falling through gaps,” laments McAvoy in the clip. “I need to get back…my life. I’m not going mad. Am I?!”
As well as McAvoy, Neverwhere features an all-star cast including Benedict Cumberbatch, Anthony Head, Bernard Cribbins and Christopher Lee.
The six-part series begins with an hour-long episode at 2:30pm on Saturday 16 March on Radio 4 and continues with five 30-minute instalments stripped across the week at 6pm on Radio 4 Extra from Monday 18 March.
