Trivia

At the 2017 Cannes Film Festival, Adam Sandler and Ben Stiller stated in a press conference that playing brothers in this movie was one of the best experiences they've ever had in their careers, as it allowed them to grow closer as friends than they ever have in the past.

Adam Sandler stated in an interview that he enjoyed working on this movie so much that he would do another movie with writer, producer, and director Noah Baumbach as soon as he offered it to him. He was quoted saying "If Noah has an idea, I'm in."

Elizabeth Marvel revealed that John Cazale's performances in The Godfather (1972) and The Godfather: Part II (1974) was one of her main inspirations for how she portrayed Jean.

This movie and Okja (2017) generated some controversy after being selected for the competition line-up of the 2017 Cannes Film Festival, due to the fact that, as Netflix productions, they wouldn't receive a theatrical release in France after the festival. Netflix did try to make a deal with French distributors and cinema chains for a limited release prior to the streaming premiere, but this was hindered by strict French laws which prevent any movie that's released in cinemas from being available on a streaming service prior to thirty-six months after the original theatrical release date. Although both movies were retained in the competition line-up, the festival did respond to the controversy by amending its rules, specifying that, starting with the 2018 edition, all filmmakers and producers submitting their work for consideration for the competition must be committed to obtaining regular theatrical distribution in France.

Despite playing the youngest sibling, Ben Stiller is older than Adam Sandler and Elizabeth Marvel.
