Made for 4 Extra. The best-selling author and uber-producer discuss The Sandman, Hitchhikers and Good Omens.

The best-selling author Neil Gaiman and the uber producer Dirk Maggs go back a ridiculously long way, but they only actually met in person a few years ago.

Their friendship began during the early days of email when, in 1992, Dirk wrote to Neil asking if he could turn Gaiman's 'The Sandman' comic series into a radio play.

Sadly that project didn't happen, but it was the beginning of a long friendship, which led to their working together on the hugely successful 2013 radio drama Neverwhere and, most recently, on BBC Radio 4's adaptation of Good Omens, the cult classic written by Neil and Sir Terry Pratchett.

Recorded in September after the read though of Good Omens.

Produced by Liz Jaynes.
