Matt Smith, 27, grew up with his family including one sister in Northampton. He was head boy at Northampton School For Boys where he excelled at sports, music and drama.

Initially, Matt wanted to be a professional footballer and played for Northampton Town Under 11 and 12s, Nottingham Forest Under 12,13,14s and Leicester City Under 15 and 16s before a back injury forced him out of the game.

Following his injury, and with the encouragement of one of his teachers, Jerry Hardingham, Matt decided to join the National Youth Theatre. It was during this time that Matt first gained attention at the Royal Court Theatre when he was cast in the play Fresh Kills, directed by Wilson Milam, whilst still at the University Of East Anglia where he was studying Drama and Creative Writing.

Already a stalwart of the National Youth Theatre, his performance at the Court led to a variety of theatrical experiences at the National Theatre: in the award winning History Boys (directed by Nick Hytner), On The Shore Of The Wide World (directed by Sarah Frankcom) and also in the acclaimed trio of plays Burn / Citizenship / Chatroom (directed by Anna Mackmin).

These roles led to Matt's first outings on the small screen, alongside Billie Piper in Phillip Pullman's period detective stories, The Ruby in the Smoke and The Shadow in the North, where he played Jim, right hand man to Billie's detective heroine Sally Lockhart. These pieces were followed by the lead role of Danny in the BBC Two series Party Animals, the brilliantly observed drama set in the world of young politicians.

In a dazzling return to the Royal Court in 2007, Matt played Henry in Polly Stenham's award winning first play That Face, opposite Lindsay Duncan. His performance gained Matt an Evening Standard Best Newcomer nomination and a year later the play had a second life in the West End at the Duke of York's Theatre. In between the two runs, Matt played Guy opposite Christian Slater's Buddy in Swimming With Sharks, Mike Leslie's searing West End adaptation of the 1994 Hollywood film. In this time he also played a lead role in the BAFTA winning BBC One series, The Street, opposite Gina McKee and Lorraine Ashbourne.

Matt could recently be seen in Moses Jones for BBC Two, directed by Michael Offer, in which he played the lead role of Dan Twentyman, alongside Shaun Parkes in the title role.

As of July 2009 Matt began filming his role as the Doctor in South Wales. Filming will continue until March 2010 and the series will air in the UK on BBC One in Spring 2010.
