Trivia: The directors have previously worked on both Community and Arrested Development - both shows get nods in this movie. Jim Rash, the Dean from Community, plays an MIT faculty member at the start. More subtle is the Bluth family's stair-car from Arrested Development, seen briefly as Captain America walks onto the airport runway before the big battle with the other Avengers.
Trivia: SPOILER WARNING. The character of Kevin was originally intended to be in the film "Unbreakable" (to which this film is revealed to be a sort-of sequel in the final twist scene), but he was removed for thematic reasons, as it was felt that his presence took away focus from that film's true villain "Mr. Glass." Writer/Director M. Night Shyamalan has stated his intentions to make a third film in the "trilogy" that will feature Bruce Willis' character David Dunn from "Unbreakable" being forced to confront Kevin, who will be his ultimate "supervillain."
Trivia: The movie was filmed in secret and revealed in 2015, when it was shopped around to distributors. Netflix acquired the movie and released it as a Netflix-exclusive title in 2016. However, it was removed from the service in 2023 once the initial licensing deal expired. Director Mike Flanagan has stated his intention to try and shop the film around for a physical media release on DVD/Blu-Ray in the near future.
Trivia: Jason Bourne only has 45 lines of dialogue in the entire film.
Trivia: Even though they play mother and daughter, Michelle Borth is only eleven years older than Nichole Bloom.
Trivia: During the real Deepwater Horizon oil spill, actor Kevin Costner offered his services, claiming that a small company he bought from the U.S. Department of Energy could clean up 90% of the oil in a week, using poorly-tested technology. His offer was accepted, despite zero evidence that the technology ever worked; and it failed miserably, of course.
Trivia: The line "he'll stop doing it" "stop doing what?" followed by violence was used almost identically in Iron Man 3, also written and directed by Shane Black.
