"Bird Box" is a post-apocalyptic horror thriller film released on Netflix in December 2018. The film is directed by Susanne Bier and is based on the 2014 novel of the same name by Josh Malerman. It stars Sandra Bullock, Trevante Rhodes, John Malkovich, and Sarah Paulson, among others.

The story is set in a world where a mysterious supernatural force has caused mass suicides. Anyone who looks directly at the mysterious entities goes insane and dies by their own hand. To survive, people must wear blindfolds or keep their eyes covered when outside. The protagonist, Malorie (played by Sandra Bullock), is a mother of two children and must embark on a perilous journey down a river to reach a potential safe haven.

The film uses a non-linear narrative, alternating between the present-day journey and the past events that led to the apocalyptic situation. It explores themes of motherhood, survival, and human nature under extreme circumstances.

"Bird Box" received significant attention upon its release and became a cultural phenomenon, sparking numerous discussions and even inspiring internet challenges where people attempted to do everyday tasks blindfolded. While it received mixed reviews from critics, it was a commercial success and was widely watched by audiences around the world.
