His computer game credits include the voices of Nowe in Drakengard 2, Xavier in Rule of Rose, and Horace in The Last Story.
James has also recorded a number of unabridged audiobooks including Alan Hollinghurst's The Stranger's Child, the follow-up to his Booker Prize winning The Line of Beauty.
"Wilson is a triumph, bringing character's voices recognisably from childhood to old age... mesmerisingly examined for meaning," said Karen Robinson of The Sunday Times on his reading of The Stranger's Child.
Other titles include John Boyne's Crippen, Herbie Brennan's The Ruler of the Realm and Faerie Lord, F. E. Higgins' The Eyeball Collector, The Bone Magician and The Black Book of Secrets, which received the Merit award at the CBI Book of the Year Awards, Matt Haig's The Runaway Troll and Shadow Forest, Janet Foxley's Muncle Trogg and the role of Cooper in Mike Gayle's The Life and Soul of the Party.
For years, James played Paul, one of the new generation of The Tomorrow People in the audio series by Big Finish Productions.
