With Mark Lawson

Dramatist Jez Butterworth talks about the pressures of following on from the success of his play Jerusalem, which starred Mark Rylance. His new play The River stars Dominic West and is being staged in a very small theatre. Jez Butterworth explains the choice of venue, and the unusual ticketing arrangements introduced to cope with demand.

Doctor Who and Sarah Jane Adventures writers Russell T Davies and Phil Ford have created a new action thriller, Wizards vs Aliens. In the CBBC series, a 16 year old wizard and his best friend are the only people who can protect Earth from magic hungry aliens. Novelist Matt Thorne and his young son give the verdict from different generations.

The idea of music on the move has inspired two specially-commissioned soundscapes to fit specific journeys. Portishead guitarist Adrian Utley has created a piece of music for the National Trust, to accompany a walk at Croft Castle in Herefordshire, and composer Philip Sheppard has written a score to accompany the Gatwick Express rail route between Victoria and Gatwick Airport. They discuss the art of responding in music to very specific locations.
