Stories from the set

James Gunn specifically made the film with little-known villains because he believed it would better convey the spirit and atmosphere of John Ostrander's original comics. Here is how he explained it: "I wanted to show second-tier villains, just like in the original comics. There is something tragic about it – in supervillains who, even in villainy, have not achieved much success."

James Gunn mostly used practical effects. He himself said that it brings him pleasure after working on the films in the Guardians of the Galaxy franchise, which had a lot of computer graphics.

An error was made in the domestic localization; in this case, the correct spelling is «Mission on Takeoff».

According to director and screenwriter James Gunn, the largest sets in Warner Bros. history were built for the film.

Director James Gunn compared the relationship between Harley Quinn (Margot Robbie) and Bloodsport (Idris Elba) to the comedy duo of Bud Abbott and Lou Costello.

According to John Cena, James Gunn asked him not to read Peacemaker comics before filming. As a result, Cena began performing the role in the style of a tough sergeant from the film "Full Metal Jacket," but Gunn soon told him to play a more jokey, cocky, and overly familiar version of Captain America from the Marvel Cinematic Universe.

Director and screenwriter James Gunn said that the resulting image of Peacemaker (played by John Cena) reminds him of characters from 1970s comic book adaptations, such as «Wonder Woman» and «Captain America».

In this film, director and screenwriter James Gunn removed the «Rotten» tattoo on Harley Quinn's (Margot Robbie) face that could be seen in previous DC Extended Universe films, because neither he nor Robbie liked it.

Director James Gunn said that each member of the squad was inspired by different film genres. For example, Bloodsport, played by Idris Elba, is based on 1960s action heroes, in particular the characters of Steve McQueen.

Idris Elba was originally set to replace Will Smith as Deadshot, but the character was changed to Bloodsport to allow Smith to return to the character in the future.
