But here, Anderson's mannered framing and meticulous period style still allows plenty of breathing space for its love story - that of two 12-year-old runaways, Sam and Suzy (Gilman and Kara) who start out as penpals and take off together into the gentle wilds of New Penzance Island off the New England Coast.
That's after bespectacled bullied Sam goes awol from his scout camp on the island and Suzy packs her things (fantasy books mostly) and escapes the island house where her parents (an equally droll McDormand and Murray) endure a crumbling marriage while fretting about raising their brood of bookworms.
As the two young lovebirds set up camp in an idyllic cove they name "Moonrise Kingdom", their absence throws Suzy's folks, as well as the local island cop (Willis, terrific), Sam's scoutmaster (Norton, hilarious) into a panic.
That brings in "Social Services" (a typically icy Swinton resplendent in a Salvation Army bonnet) to the island too - Sam's an orphan and his foster family aren't keen on getting him back. Add Harvey Keitel and Jason Schwarzman to that ensemble and it becomes a little crowded as this heads towards an ending that does undo a little of the understated magic of what's gone before.
But for the most part, Moonrise Kingdom is a whimsical wonder.
