With wry humor and affection, Simon Ennis’ “Lunarcy!” follows a disparate group of dreamers and schemers who all have one thing in common: they’ve devoted their lives to the Moon. From the young man who’s resolved to depart for Luna (permanently) to the ex-ventriloquist who’s made millions selling Moon lots, “Lunarcy!” is a funny and touching portrait of passion, creativity and quixotic dreams.
