Dash Shaw's 'My Entire High School Sinking into the Sea' is set to screen at the Toronto and New York film festivals

It’s been a pretty good 12 months for animated movies for adults, from the dirty-talking edibles of Sausage Party to the existential comic angst of Anomalisa to the wordless, elegiac beauty of the Cannes Film Festival hit The Red Turtle. Get ready to add another to that list.

My Entire High School Sinking into the Sea has been described as a mixture of Ghost World and The Poseidon Adventure. The line-drawn comedy-drama about the richness and complexity of friendship premieres this weekend at the Toronto International Film Festival and is directed by Dash Shaw, a graphic novelist best known for his books Bottomless Belly Button (named the #5 best book of the year by EW in 2008), BodyWorld, and New School and this gorgeous 7-minute Sigur Rós music video Seraph.

For his feature-length debut, Shaw has assembled a stellar voice cast that includes Jason Schwartzman, Lena Dunham, Reggie Watts, Maya Rudolph, Margo Martindale, Susan Sarandon, Alex Karpovsky, and John Cameron Mitchell. The two-and-a-half-minute scene above, featuring Rudolph, Watts, and Schwatzman floating in a water-filled classroom, gives viewers a sense of Shaw’s deadpan absurdism. “If you say something smells,” remarks Schwartzman’s character, “you don’t have to say it smells bad.”

After its world premiere in Toronto on Sept. 11, the film will then screen as part of the New York Film Festival later this month. No release date has been announced.
