Talk To Rex is James Aylett and James Lark.

James Aylett first appeared at the Edinburgh Fringe in 1995, wailing loudly and wearing a dress. As an undergraduate he performed and wrote regularly for the Cambridge Footlights, as well as taking roles in the usual swathes of Shakespeare, Shaffer and Ibsen, before squirrelling himself away in the world of advertising where he had a tendency to invent things and give them really obscure names. Having developed an interest in film making and even spent a month in New York especially to learn about it, he has more recently turned to the (somewhat affordable) medium of the short film. A co-founder of improvisation group The Uncertainty Division, he has directed a number of the group's narrative shows, and performed in all of them, appearing across the country in a variety of guises, many of them wailing loudly and wearing a dress.

James Lark works sporadically as an actor, writer and musician, occasionally combining all three such as in his 2006 Edinburgh show The Rise and Fall of Deon Vonniget, a culmination of years of traipsing around venues all over the country singing comic songs about cheese. But he has done some serious plays as well, and when not acting in them he is usually directing the music for them. He has written for Ealing Live!, Focus Theatre Company and The Friday Thing and one of his monologues on BBC Radio won a Jerusalem Award in 2004. He has had music performed all over the world by the likes of English Voices, Girton College Choir and the organist Guy Bovet. He has co-written, directed and scored several short films, and written a couple of features which are now gathering dust. Although he co-founded The Uncertainty Division and has performed in all of their shows, he is a different person to James Aylett.
