Haunted by the violent demise of their parents 10 years earlier, adult siblings Kaylie and Tim are now struggling to rebuild their relationship. Kaylie suspects that their antique mirror, known as the Lasser Glass, is behind the tragedy. The seemingly harmless reflections contain a malevolent, supernatural force that infects the mind of anyone who gazes into it. As Kaylie gets closer to the truth, the siblings become caught in the mirror's evil spell.
On October 27, 2012, filming wrapped in Fairhope, Alabama, after three weeks. The film is based on Flanagan's earlier 2005 short horror film, also called Oculus. Initially, studios were interested in making the film in accordance with the found footage genre; however, Flanagan was opposed to this and passed on such offers. Eventually, Intrepid Pictures expressed interest in producing the film "as long as you don't do it found footage".
The film was first released on September 5, 2013, at the 2013 TIFF, and received a worldwide theatrical release on April 11, 2014. The film was released on DVD and Blu-ray Disc on August 5, 2014.
The soundtrack to Oculus was released digitally on April 8, 2014 and on CD on April 15, 2014. The songs were produced by Bryon Davis.
In March 2015, Relativity Media, B4U Television Network, and Balaji Telefilms confirmed a Bollywood remake with the title Zahhak. The title was later changed to Dobaara: See Your Evil. This film is directed by Prawaal Raman and stars Huma Qureshi and Saqib Saleem in the leading roles. Director Mike Flanagan served as the executive producer. The film was released on June 2, 2017.
