Trivia: Sonic makes a brief joke about the feud between the actors Vin Diesel and Dwayne Johnson, who both appeared in the "Fast and Furious" movie franchise. This film is from the same producers as that franchise.
Trivia: When the Tyrannosaurus Rex walks past the circular shaped waterfall, it lines up perfectly recreating the Jurassic Park movie logo.
Trivia: Sweet Pete's tragic backstory is similar to Bobby Driscoll who voiced Peter Pan in the original Disney film. Many people have expressed disgust over this, as it distastefully satirizes Driscoll's own personal tragedy and downfall of being unable to find work after getting older.
Trivia: When Nancy Tremaine (Idina Menzel) is singing to Morgan about her memories to make the tree come to life again she sings a line "Let it glow, let it glow." This is an homage to Idina Menzel as Elsa in Frozen singing "Let it Go".
Trivia: Doctor Strange casts a spell on the pizza vendor, played by Bruce Campbell, that forces him to repeatedly hit himself. This is similar to a scene from Evil Dead II, which sees Ash, also played by Bruce Campbell, attacked by his own possessed hand.
Trivia: This was filmed back to back with the as-yet-untitled Avatar 3. But filming didn't start until the scripts were written for 2 further sequels, so the actors would know the paths that their characters were on. James Cameron allocated the scripts to different writers after months of meetings and storyboarding. He didn't tell the writers which script they'd be working on until the end, because he knew "they'd tune out every time we were talking about the other movie."
Trivia: Nolan North, who does motion capture in the games for Nathan Drake, is on the beach at the resort. He asks Nate and Chloe what happened, and they say they fell out of a plane. He says that happened to him once. He's referring to the third game in the Uncharted series where similar events happen.
Trivia: Winston Duke's line "you bald-headed demon" was improvised.
Trivia: The "wolf woman" seen in the montage at the start is played by Chris Hemsworth's wife Elsa Pataky.
Trivia: Sergei from Secret Life of Pets 2 can be seen in the bank.
Trivia: When Michael and Milo battle for the first time, you hear Milo repeatedly chant "Michael, Michael." It's probably my own cerebral connection, but I can't ignore the funny reference to the Lost Boys (1987) in which the main vampire (brilliantly played by Kiefer Sutherland) also chants 'Michael, oh Michael' to Michael Emerson (Jason Patric), Sam's (Corey Haim) brother, when Michael is slowly turning into a "sh*tsucking vampire" .
Trivia: In the universe where Evelyn is a movie star, real, archival footage of Michelle Yeoh from the premiere of "Crazy Rich Asians" is used.
Trivia: Chris Hemsworth, who is a producer of this film and also is married to star Elsa Pataky, has a cameo as the guy in the electronics store.
Trivia: Adam Nee, the co-director and co-screenwriter, has a cameo as Officer Sawyer.
Trivia: The studio asked Johnny Depp to resign from his role as Grindewald for this film, owing to allegations of domestic abuse by his ex-wife, Amber Heard. Depp later sued Heard for defamation and won the case.
Trivia: Towards the end when young Adam takes the light saber, he jumps and lands saying "super hero landing", as mentioned by Deadpool in his movie played by Ryan Reynolds.
Trivia: The army officers estimated that the Allosaurus had a territory measuring about the same area as that of wolves, or roughly the square miles of Rhode Island. Rhode Island is nicknamed "The Ocean State" [also, "Little Rhody"]. "The Island State" would not be an appropriate nickname because Rhode Island is not an island... but it does have four islands. As the smallest U.S. state, more than 220 Rhode Islands would fit into the second-largest state, Texas.
Trivia: The animated sequences were actually filmed in live-action with the actors on-set, and then rotoscoped with 2D animation. Director James Gunn wanted to emulate the films of Ralph Bakshi, which often employed similar techniques of live-action footage being rotoscoped with animation.
Trivia: During the end credits, you can see various drawings. One of the drawings is The Backson from Winnie the Pooh (2011), which was also directed by Don Hall.
