Trivia: Bill Skarsgård was purposely kept separated from the child-actors during filming, and outside of some early publicity photos, the kids never saw him until the first scene they filmed together in order to get their genuine reactions. The kids were both genuinely scared of him, but also incredibly excited after filming their first scene.
Trivia: In addition to the more obvious nods to the original (including the name "Alan Parish" being scratched into the hut), all of the statues in the world of Jumanji are modeled after the game-pieces and box from the original film.
Trivia: When Ana is telling Hannah, her new assistant, what she expects of her in the job, the dialogue is taken from the 1988 film "Working Girl," starring Dakota Johnson's mother, Melanie Griffith. Ana says, "I expect you to call me Ana. I don't expect you to fetch me coffee, unless you're getting some for yourself, and the rest, we'll just make up as we go along." In "Working Girl," Melanie Griffith says, "I expect you to call me Tess. I don't expect you to fetch me coffee unless you're getting some for yourself, and the rest we'll just make up as we go along."
Trivia: The film is edited by Kevin Greutert, who edited "Saw" 1-5, and directed the sixth and seventh films. Greutert is one of only a few holdover crewmembers from the original run of the series to return. He said he felt an obligation to be a part of "Jigsaw"- feeling that given his past with the series, he should help usher the franchise into the new direction that the producers and writers wanted to take, while also helping to maintain ties to what came before.
Trivia: The severed heads in the guillotine basket are of the film directors Joachim Rønning and Espen Sandberg.
Trivia: Vin Diesel was given a special "Groot" version of the script that contained "translations" of what Groot was actually saying whenever he utters his one and only repeated sentence "I am Groot." This was done to help him deliver his dialog appropriately, since he would know exactly what point Groot was trying to get across with each line. Reportedly, only Diesel was given this version of the script - in everyone else's script, Groot's dialog is merely "I am Groot" over and over again.
Trivia: Taron Egerton refused to shoot the scene where he implants the tracking device into Charlie's girlfriend's groin, as he felt uncomfortable touching the actress in that area. The hand we see reaching down into the woman's underwear is actually the hand of the actress' husband, who gladly volunteered to "double" for Egerton's hand in that scene.
Trivia: There were rumors right up until the release that the film was a prequel to the 2004 superhero movie "Hellboy" - in no small part because both films feature an amphibious man played by actor Doug Jones as one of the lead characters, and both films were also directed by Guillermo del Toro. Despite the widespread speculation, del Toro consistently denied any plot or character associations between "The Shape of Water" and the Hellboy films.
Trivia: Igon Sirruss tells Valerian "I will find you and I will kill you," to which Valerian replies "Good luck." This dialog exchange is taken almost word-for-word from the film "Taken" as a bit of an inside joke, as "Valerian" director Luc Besson was also the producer and co-writer of the "Taken" film trilogy.
