The Lieutenant of Inishmore (2006)

Martin McDonagh (The Pillowman) cribs shamelessly from hyperviolent indie caper films, overdoes the Grand Guignol sanguinary spray, and indulges his psychotic characters with Tarantinoesque gunpoint ramblings — all things a formal education would have drummed out of him. Fortunately, McDonagh never had a formal education. The Lieutenant of Inishmore, the second play in his Aran Islands trilogy — focusing on a ferociously inept IRA splinter group and the disastrous assassination of a pet cat — was written in the mid-'90s, but it's a mordant, marvelous, and all-too-current comedy of terror.
