In Ari Aster's folk horror film, Midsommar, a couple on the verge of breaking up finds themselves entangled in the strange rituals of a pagan cult. It all starts after Dani (Florence Pugh) loses her entire family in a tragic murder-suicide, and she ends up tagging along on a trip to Sweden with her inattentive boyfriend, Christian (Jack Reynor), and his friends, Mark (Will Poulter) and Josh (William Jackson Harper). They were invited by their classmate, Pelle (Vilhelm Blomgren), who comes from a small Swedish community known as the Hårga. He wants the group to join them for the community's sacred Midsommar festival ... but Dani slowly come to find that this is no friendly gathering.
Unlike Aster's previous film — the incredibly disturbing Hereditary — Midsommar is the rare horror movie in which the terror plays out under broad daylight. On top of that rare distinction, the film is packed with symbolism and Easter eggs that might not be obvious, even to eagle-eyed viewers, upon their first watch. But if you return to the film and pay close attention, you're bound to notice the many hidden clues that Aster cleverly concealed in background imagery. Plus, you might pick up on a few throwaway lines that hinted at deeper, darker meanings. If you're brave enough to watch Midsommar a second time, you should definitely keep an eye out for these details.
(Be warned — we're spoiling the entire movie.)
