Trivia: When Roy McBride is reviewing a top-secret message regarding his father and the LIMA mission, the message filename is "6EQUJ5," which is a very obscure easter egg in the movie. The filename 6EQUJ5 refers to the real-life "WOW Signal," a deep space radio signal received by the Big Ear radio telescope at Ohio State University in 1977. The alpha-numeric designation "6EQUJ5" was a printed readout of the signal's duration and intensity. This signal lasted 72 seconds and was 20 times stronger than background radio noise, causing a surprised astronomer to circle the printed 6EQUJ5 readout in red ink and make the handwritten notation "WOW!" in the margin. While the signal was an anomalous one-time event that was never repeated, and there is still no proof that 6EQUJ5 was alien in origin, it has stimulated debate about extraterrestrial radio signals for decades. Ironically, the movie "Ad Astra" concludes that there are no alien radio signals and that we really are alone in the universe.
Trivia: K Callan, who plays Christopher Plummer's mother in this film, is actually six years younger than Plummer in real life.
Trivia: During one epic car crash near the start, just after the shooter gets taken out by the digger, if you know what to look for you can see Ryan Reynolds in the background, filming a post/advert for social media. Not a mistake, because it's just a tiny figure at the back of shot, but pairing the film and the post together it's fun to look for. (00:14:42)
Trivia: "Child's Play" creator Don Mancini has no involvement in this remake, and has openly stated that he's against it, as the original movie series is still going. Several other key cast and crew members from the original series have also expressed their disapproval of the film.
Trivia: The third act was completely changed after reshoots. The final battle originally took place in space, and was then relocated to a train.
Trivia: Ella Balinska performed many of her own stunts in this movie.
Trivia: There's an homage to Beauty and the Beast as Timon starts singing: "It is with deepest pride and greatest pleasure that we welcome you tonight. And now we invite you to relax let us pull up a chair as the dining room proudly presents your dinner!" They then show Pumba as the dinner to the hyenas. Pumba was the distraction when Simba came back to the Pridelands. (01:45:00)
Trivia: The director only came across Jonathan Pryce because he was searching for photos of Pope Francis, and the two people were frequently being compared as they look so similar. He looked into Pryce's body of work and realised he'd be an excellent choice for the part.
Trivia: When we see Abra's house, the number on the front is 1980. That was the same year the original Shining was released.
Trivia: Matt Damon's primary reason for taking the part was because he was keen to work with Christian Bale.
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 mysterious processed voice of The Director is actually that of Ryan Reynolds, under his pseudonym of Champ Nightingale. Which doesn't necessarily mean his character is the primary antagonist. But might.
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.
