Trivia: In the entire film, there are only two "homegrown", real humans - Tank and Dozer. They both have names of machines.
Trivia: The two old men near the end, talking about it being "old school" are voiced by Frank Thomas and Ollie Johnston, two Walt Disney animators who worked on such classics as Bambi and Cinderella.
Trivia: John Rhys-Davies is missing the end of his middle finger on his left hand due to a farming accident as a child. The make-up artists made artificial, gelatin fingertips for him to wear in the movies. Davies one day, cut the tip in half, put 'blood' in it and closed it up. He went over to Peter Jackson (unaware of the gelatin tip) and said, "Boss, I've had an accident, look what happened". Jackson saw a small cut, but Davies bent the tip back and it split open, gushing.
Trivia: Laurence Mason's character Lord Nikon was given the name because of his photographic memory.
Trivia: When the Japanese are heading towards Pearl Harbor, there is a shot of a pilot waving to kids playing baseball. This is a true story - the pilot was trying to wave them away before the attack started. (01:26:35)
Trivia: While on the helicarrier, Tony Stark is wearing a Black Sabbath T-shirt, the band who released the song "Iron Man".
Trivia: A great deal of Flint Marko/Sandman's storyline was edited out of the film by the studio due to the long run-time. One scene early in the film showed that the scientists who accidentally created Sandman were racked with guilt when they discovered they might have activated the machine with a person inside of it. Another scene had Sandman visiting a doctor researching his daughter's rare disease whom he had been corresponding with in prison. Yet another scene showed him following his daughter in a park, and morphing into a giant sandcastle that she plays with. And finally, his daughter was going to appear in the final battle, and would appeal to her father to stop hurting people and living a life of crime to get money, as she accepted that she was going to die no matter what. Her words would be what convinced him to seek forgiveness from Peter for accidentally killing Uncle Ben.
Trivia: The Korean woman whom Cris calls up during his magic act is actually the real-life wife of Nicolas Cage.
Trivia: The first MCU movie to feature the word "fuck", when Quill tells Nebula to "open the fucking door", a line that was improvised on-set and kept in because it was so funny. James Gunn anticipated being told to cut it out, but Kevin Feige left it up to Gunn's discretion. Feige said the Russo brothers had a "fuck" in an early cut of Avengers: Endgame, but they "didn't want that to be their legacy, so if you want that to be your legacy, then sure." James Gunn said that just made him even more keen to keep the line in, at which Feige "laughed his ass off."
Trivia: Red Grant has no dialogue until he first meets Bond. He first speaks in a rich, upper-class English accent. After Grant has revealed his true identity to Bond, his English accent changes into a lower-class Irish accent as he explains the SPECTRE background plot.
Trivia: In the film, Bond says to M, "So you want me to be half-monk, half-hitman." This is a reference to the character John Ballard (played by Daniel Craig) in the 1998 film "Elizabeth".
Trivia: Edward Hyde tells Nicholas that he is a younger man. In real life, Tom Cruise is two years older than Russell Crowe.
Trivia: Not really a mistake, given the need to maintain the story arc in the first half of the film, but in real life, Pyle would have been discharged from the Marine Corps within days of his starting basic training - for his own good. It happens all the time - dropout rate of boot camp recruits varies but is generally around 10%.
Trivia: Cary Joji Fukunaga is the first American to direct an official Bond movie.
Trivia: The Titans first encounter Slade while he's stealing a power crystal. They mistake him at first for the Marvel character, Deadpool and proceed to argue back and forth about him being Deadpool or not. With him saying that he's not Deadpool, that actually Deadpool should be saying he's not Slade. This is a joke and reference to the fact that the designer of Deadpool based his looks, abilities, and character originally off Slade/Deathstroke because he wanted to draw Deathstroke. Until Deadpool's backstory and personality were changed to what we know him as today.
