A mental patient pretending to be an alien, a gullible town and the director of ‘Once’: ‘Zonad’ offers some goods.

Irish films generally fall into a few limited categories. There’s the dark and dour movies that explore their troubled history with the IRA (Bloody Sunday), films that focus on abuses at the hands of misguided and violent authority figures (The Magdalene Sisters), movies where people sing bad songs poorly (Once), and then there’s the whimsical fantasies about seal people attempting to enslave humanity (The Secret of Roan Inish). That’s it really. But now a fifth category can be added to the official Irish film canon… zany comedy!
