Knives Out, Rian Johnson's acclaimed 2019 murder mystery, is due to leave Peacock in the United States at the end of August 2026, prompting Collider to flag it as a must-watch before it disappears. The film is widely credited with reviving the modern murder-mystery genre, paving the way for Netflix's Glass Onion and Wake Up Dead Man sequels, as well as a broader wave of whodunnits including The Sheep Detectives, A Good Girl's Guide to Murder and Agatha Christie's Seven Dials.

Knives Out grossed roughly $312 million worldwide on a modest budget and led Netflix to pay a reported $400 million for two sequels, released in 2022 and 2025 to strong reviews. The genre's resurgence is traced back further to 2017's Murder on the Orient Express, which took around $350 million globally and spawned its own sequels, with 2026's The Sheep Detectives ($130 million worldwide against a $75 million budget) cited as the latest hit in the trend.
