“Apocalypse Clown” (*1/2 out of four) was a tiresome comedy set in Ireland about a mysterious technological blackout that plunges the country into chaos; realizing that the end of the world may be near, a group of washed-up clowns (David Earl, Natalie Palamides, and others) travel the country for one last attempt at achieving their clown dreams. Good-natured but innocuous movie is a one-joke premise stretched well beyond its lengths at nearly two hours. Some good visual stylistics can’t save it. Even still, this won the Best Film Award at the Galway Film Festival this past summer.
