Do you know who your friends are? Sure, you may associate with various other humans in your day-to-day existence — a mother here, an over-friendly co-worker there — but do you really know them? Are you 100% sure that Lawrence from the office isn’t really a harp seal in disguise? I ask this because the Selkie menace is at an all-time high. The last big Selkie resurgence was in 2010, when the Colin Farrell flick Ondine made brief mention of them. Before that was 1994, and The Secret of Roan Inish, also with Selkies. Oh, and for the uninitiated: Selkie (sel-kie) n. A creature or spirit in Scottish and Irish folklore that has the form of a seal but can also assume human form. (Thanks, free internet dictionary.) In greater detail, they’re seals that, when underwater, look and act totally like seals. But they also have the ability to strip all that sealskin off their bodies and blend in with us human folk. Traditionally, they tend to target humans in unsatisfying relationships, only to romance them and leave them hanging when they inevitably throw their living seal costumes back on and return to the ocean. Now they’re back thanks to Tomm Moore, the guy who previously printed a giant exclamation mark on the animation world with 2009’s The Secret of Kells. He’s given new life to the Selkie scourge with his newest film, Song of the Sea.
