Cox and O'Hanlon on The Weir

26 January 2014 Last updated at 11:57 GMT

Actors Ardal O'Hanlon and Brian Cox told Andrew Marr that ghosts and ghost stories pervade the remote Irish pub which is the setting of Conor McPherson's acclaimed play The Weir.

O'Hanlon described the play, in the second week of a new West End run, as a snapshot of a community in a remote area which is both about "notions of Irishness" but also about the "universal and timeless" themes of loss and loneliness.
