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, only to find themselves in the clutch of a 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 this concept but made a deteriorating relationship the central conflict after he had experienced a difficult breakup. The film was shot on location in Budapest, Hungary in the summer and fall of 2018.
Midsommar was theatrically released in the United States on July 3, 2019. It received positive reviews from critics, with specific praise for Aster's direction and Pugh's performance.
