Trivia: The film had a surprisingly fast production schedule. While the movie was announced shortly after the previous film, filming didn't begin until the end of January, 2019. The movie wrapped in May - only seven months before the release. By contrast, the previous film, "Welcome to the Jungle," wrapped filming a full year before release.
Trivia: The movie was filmed in a full-frame aspect ratio and in black and white in order to help put the audience into the film.

Trivia: Original "Hellboy" film series director Guillermo del Toro tried for nearly ten years to get a third film made in the series. However, due to a variety of circumstances, including budgetary concerns, his original vision for the third film was unable to be made. This movie was then written by series creator Mike Mignola and writer Andrew Crosby, with the intention of following on from the first two films. However, del Toro and original star Ron Perlman declined to be involved, feeling they should not make the film as it wouldn't pay off the storylines set up by the first two movies. Mignola and the producers then decided that rather than trying to make a direct sequel to the first two films without del Toro and Perlman, it should be rewritten to be a stand-alone reboot. References to the other films (and certain characters like Abe Sapien and Liz Sherman) were removed, and replaced with new concepts to set it apart from what came before.
Trivia: Series star Warwick Davis reportedly turned down the opportunity to star in the film. He stated that as he now has children, he wanted to focus on non-horror projects for the time being. Though he also hinted that he would like to return to the genre once his kids get older.
