The zero gravity scene took sixty-four takes and was shot for two days in a falling plane. Reportedly, a lot of the crew got nauseous during the scene and vomited, except for the main stars, Tom Cruise and Annabelle Wallis, who were really proud of the stunt.

When Jake Johnson was offered his part in the movie, he loved the idea and the opportunity to work with Tom Cruise, knowing that Cruise does most of his own stunts. He signed on immediately, but when he read the full script and learned what kind of dangerous actions were expected of him, he admitted to getting cold feet. However, Cruise allowed Johnson access to his private facilities for a rigorous 4.5 month training course, making him well prepared for all the stunts he was required to do.

This film is intended to be the first installment in a possible Universal Monsters shared universe, also known as "Dark Universe."

The film's tagline, "Welcome to a new world of gods and monsters," is a quote from Bride of Frankenstein (1935), which was also produced by Universal and will be the next installment in the Dark Universe franchise.

After promoting the film on The Tonight Show Starring Jimmy Fallon: Tom Cruise/Kate Mara/Bleachers (2017), Tom Cruise surprised the audience by inviting them to the premiere of the film immediately after the interview, transporting them in shuttle buses.

Director Alex Kurtzman stated that there is no post credits scene because "That's Marvel's domain."

The Mummy's design and gender were altered to avoid similarity with the titular villain of X-Men: Apocalypse (2016).

Javier Bardem, Joseph Gordon-Levitt, Tom Hardy, and Eddie Redmayne were all considered to play Henry before Russell Crowe was cast in the role. Bardem was then cast as Frankenstein's Monster in a planned sequel.

A big fan of Peaky Blinders (2013), Tom Cruise personally requested Annabelle Wallis to audition for the film.

When Universal was planning their Dark Universe franchise they originally envisioned Dracula Untold (2014) as the first installment with this film being the second. That film ended with Dracula in modern day times while the Master Vampire "Let the games begin" in a very obvious set up for future installments. There was early talk about Dracula appearing in this film. However, as this film progressed it was cited as the first in the Dark Universe leaving the earlier movie to exist on its own. While Dracula director Gary Shore said he hoped the possibility that his film would join the universe was left open Mummy director Alex Kurtzman said it would not be canon.

The Mummy had a relatively disappointing box office run, grossing just over $400m worldwide. Studio sources have said that Tom Cruise exerted too much control on the set, and that his input into editing and marketing greatly changed the pace and style of the movie.

The film's original plot was set in Iraq and followed a Navy SEAL and his team that battle mummies led by Ashurbanipal.

As of May 22, 2017, Universal Studios officially called their new monster universe the "Dark Universe." This was also hinted at in the third trailer.

This film's tagline, "A new world of gods and monsters," is taken from a line in Bride of Frankenstein (1935), which featured the original Mummy, Boris Karloff. This line also inspired the title of the film Gods and Monsters (1998), which starred Brendan Fraser, star of the 1999 film The Mummy (1999).

Princess Ahmanet (Sofia Boutella) is not the first female mummy in the Universal Monsters. Before her are: The Mummy (1932), Imhotep (Boris Karloff) searched across millennia for his mummified lover, Ankhesenamun (Zita Johann), who had been reincarnated as Helen Grosvenor. The Mummy's Hand (1940), Kharis (Tom Tyler) had hoped to resurrect his beloved, the mummified Princess Ananka (Zita Johann, archive footage). Before he could, however, he was caught, and for his unholy transgression Kharis was cursed to be an undead mummy forever. The Mummy's Tomb (1942), although Ananka was absent in this film she did appear in The Mummy's Ghost (1944), reincarnated as Amina Monsouri (Ramsay Ames). When Kharis (Lon Chaney Jr.) eventually captured Amina, she transformed into the 3,000 year old mummy of Princess Ananka. The Mummy's Curse (1944), Princess Ananka's mummy (Virginia Christine) clawed her way out of a muddy grave before being transformed once again into a beautiful woman.

Len Wiseman was originally set to direct but dropped out before production began. Wiseman was then replaced by Andy Muschietti, but he also later dropped out due to creative differences.

Universal was once the reigning studio of horror films. Starting with Dracula (1931) and all through the decades was known as such to the present.

Writer Christopher McQuarrie directed Tom Cruise in Jack Reacher (2012) and Mission: Impossible - Rogue Nation (2015).

Released 85 years after the original The Mummy (1932).

The set designers initially wanted a C130K as this was the RAF's SF aircraft. Due to the wrong internal designs being received the aircraft featured is a mash-up of 2 different aircraft. The outside is a copy of the C130K and the inside is a copy of the A400M.

The character played by Tom Cruise was originally named Tyler Colt, but this was ultimately changed to Nick Morton.

The film was partially filmed in London, England, with principal photography taking place from April - August 2016.

The release of this film and American Made (2017) mark the first time Tom Cruise has appeared in more than one film per year since 2012. In 2012, he starred in both Rock of Ages (2012) and Jack Reacher (2012).

The first live action Mummy film to be released since The Mummy: Tomb of the Dragon Emperor (2008).

In Stargate SG-1, Ahmanet is the name of Apophis' Queen.

Alex Kurtzman, David Koepp, Jenny Lumet and Dylan Kussman were not revealed to have writing credits until days before the films release.

This was not Tom Cruise's first foray into the horror genre. He had played a vampire in the film Interview with the Vampire: The Vampire Chronicles (1994).

Baltasar Kormákur was offered the opportunity to direct, but turned it down.

This was the fourth "Mummy" film to receive a PG-13 rating.

This film marks Alex Kurtzman's second directorial after People Like Us (2012).

The first film Alex Kurtzman wrote without Roberto Orci.

Composer Brian Tyler composed music to The Fate of the Furious (2017) too, another Universal studio produced movie.

Annabelle Wallis has played two characters named Jenny. The first was in Mine (2016) and the second in The Mummy (2017).

The movie introduces Russell Crowe as Dr. Henry Jekyll aka Mr. Edward Hyde, which will set up the character for a standalone film in Universal's monster universe.

Just after Nick sees the skull with fangs in Prodigium, the arm of the Gillman aka Creature from the Black Lagoon can be seen floating in one of the jars to the right.

The book that Jenny knocks Dr. Jekyll's henchman out with in his library is the Book of Amun-Ra from The Mummy (1999).

Hyde calls Nick "young" during their fight scene - even though in real life, Tom Cruise (Nick) is a year older than Russell Crowe (Hyde).

There are several Easter eggs to the upcoming movies in the dark universe such as the Creature From the Black Lagoon's hand and vampire skull at Dr Jekyll's headquarters, and the Book of the Dead in his office, which made its appearance in The Mummy (1999) and The Mummy Returns (2001).

Henry Jekyll, played by Russell Crowe, plays a prominent role in this movie. Before the climactic battle scene between good and evil, Jake Johnson's character tells Tom Cruise, "This is the moment. This is the moment." "This is the Moment" is the title of the signature song from the Broadway musical "Jekyll and Hyde." Jekyll sings it just before he's about to take the potion he's designed to separate good from evil.

When Dr. Jekyll turns into Hyde, his character trades his upper class accent to a cockney accent. This trope to differentiate Jekyll from Hyde was first used in an obscure musical version of Dr. Jekyll and Mr. Hyde (1973). While Kirk Douglas' imitation of the cockney accent was almost comedic, the change in accent was later used in other adaptations, including the Broadway musical version.

Nick's relationship with his friend Chris is a direct riff off of the film An American Werewolf in London (1981). In that film David and Jack confront a werewolf. Jack is killed and David is bit. David is then haunted by Jack's rotting ghost who tells him he is cursed and add advises him what do. They also have comic banter. In The Mummy Nick is cursed by the Mummy, Chris dies, and his rotting ghost tells him he's cursed, advise him, and has comic banter.

Dr. Henry Jekyll is a character in Robert Louis Stevenson's novel, "The Strange Case of Dr. Jekyll and Mr. Hyde." He struggles with good and the bad attitudes in his life, thus creating the two different personalities, Dr. Jekyll and Mr. Edward Hyde.

Both the Mummy and Nick have moments where their eyes split from one to two irises in each eye. This is resembles the supposed condition called polycoria, also known as the double pupil pupula duplex. This medical condition may be related to other eye mutations such as heterochromia (different colored irises); but many debate on if Polycoria is a real condition or an exaggerated myth, unlike the other eye disorders.
