What with social cliques, homework, and hormones, high school is tough enough already. Add to that a massive natural disaster, and it’s a different sort of catastrophe entirely. My Entire High School Sinking Into the Sea is both exactly what it sounds like and much more than that, an animated riff on the likes of San Andreas that adds an eccentric sense of humor to the genre. The newly unveiled trailer offers a sample of the thrills (jumping across shark-infested waters!) and the laughs (the bookcase-amputation joke is aces) to be had in this odd little festival favorite.
