Don't Look Up is a 2021 American science fiction film written, produced, and directed by Adam McKay (who was assisted in the producing by Kevin Messick), and starring an ensemble cast consisting of Leonardo DiCaprio, Jennifer Lawrence, Meryl Streep, Cate Blanchett, Rob Morgan, Jonah Hill, Mark Rylance, Tyler Perry, Timothée Chalamet, Ron Perlman, Ariana Grande and Scott Mescudi. It tells the story of two astronomers attempting to warn humanity about an approaching comet that will destroy human civilization. The impact event is an allegory for climate change, and the film is a satire of government, political, and media indifference to the climate crisis.Produced by Hyperobject Industries and Bluegrass Films, the film was announced in November 2019 and sold by Paramount Pictures to Netflix several months later. Lawrence became the first member of the cast to join, with DiCaprio signing on after his discussions with McKay on adjustments to the script; the rest of the cast was added through 2020. Filming was initially set to begin in April 2020 around the U.S. state of Massachusetts but was delayed due to the ongoing COVID-19 pandemic; it eventually began in November 2020 and wrapped up in February 2021. Don't Look Up began a limited theatrical release on December 10, 2021, before streaming on Netflix on December 24. It received mixed reviews from critics, who praised the cast but were divided on the merits of McKay's satire; some found it deft, while others criticized it as smug and heavy-handed. The film has received more positive reviews from scientists. Despite the critical reception, the film was named one of the top ten of 2021 by the National Board of Review and American Film Institute. It received four nominations at the 79th Golden Globe Awards, including Best Picture – Musical or Comedy, and six at the 27th Critics' Choice Awards, including Best Picture. Don't Look Up set a new record for the most viewing hours in a single week on Netflix, and went on to become the second-watched film on Netflix within 28 days of release.
