'Macbeth' is the new Siren Production now on at The Empty Space in Temple Bar in Dublin. Directed by Selina Cartmell, it features Rory Keenan as the man himself, Barbara Brennan as his Lady Macbeth and Gerard McSorley as Duncan, King of Scotland. This being Shakespeare, it is of course a rich tale of witchcraft, power, bloodshed, corruption and no shortage of sound and fury. 'Macbeth' is at The Empty Space until Saturday.
