Matt Smith webchat – post your questions now

With a single flourish of a sonic screwdriver, Matt Smith saw his star wattage explode after he was cast as Doctor Who in 2010. For four years he battled forces across the four dimensions, leaving doomed romance, bow ties and a Bafta nomination in his wake.

Since passing the baton to Peter Capaldi, Smith has appeared in some eye-catching film roles, like the lead in Ryan Gosling’s feature debut Lost River, and an AI baddie in Terminator: Genysis. He’s performed in a number of plays - wielding the axe in 2013’s American Psycho - and now playing an obsessional film director in Unreachable, at the Royal Court.

Matt is joining us to answer your questions about Unreachable and anything else in his career. A live webchat with him will run from 1pm BST on Tuesday 12 July – post your questions in the comments below.
