Midsommar is a 2019 folk horror film written and directed by Ari Aster and starring Florence Pugh, Jack Reynor, William Jackson Harper, Vilhelm Blomgren, and Will Poulter. It follows a group of friends who travel to Sweden for a festival that occurs once every ninety years and find themselves in the clutches of a pagan cult.
A co-production between the United States and Sweden, the film was initially pitched as a straightforward slasher film set amongst Swedish cultists. Aster devised a screenplay using elements of the concept but made a deteriorating relationship the central conflict after he had experienced a difficult breakup. The film was shot on location in Budapest in the summer and autumn of 2018.
Midsommar was theatrically released in the United States on July 3, 2019 by A24 and in Sweden on July 10, 2019 by Nordisk Film. The film received positive reviews from critics, with many praising Aster's direction and Pugh's performance.
