Little Monsters (2019)

Dave has decided to get over his recent breakup by seeking refuge with his nephew Felix, accompanying him on a school trip, among other things, to be able to get closer to one of the teachers, Miss Caroline. Everything seems normal, at least until a zombie invasion breaks out that will threaten Dave's plans. New horror-movie icon Lupita Nyong'o nails it in this blend of comedy and gore.—Sitges Film Festival
