I think we might even feel a tinge of sympathy towards her this time."
The idea of self-contained minds spontaneously appearing into existence is called "Boltzmann brains." This is a metaphysical conundrum raised by quantum mechanics, and concludes that in a universe that exists forever, you are more likely to be a "Bolzmann brain" hallucinating reality than a real being.
In the Marvel Cinematic Universe timeline, the film takes place in 2014, three months after Guardians of the Galaxy (2014).

Chris Pratt said that he thought Michael Rooker has the best shirtless scene in the film. He said Rooker's shirtless scene is about showing vulnerability and developing Yondu's character. You learn something about him in the moment, but his own scene was just to show off his body, and didn't really add anything to Peter Quill.
Chris Pratt said that he found the workout regimen for his shirtless scene much easier compared to the first film, because he was already in great shape going into the film. For Guardians of the Galaxy (2014), Pratt was sixty pounds overweight when he started working out. For this film, however, he said he had maintained his buff physique acquired from the first film.

The Marvel legal department later cleared the use of Sneepers in the film, in part because of the entire media coverage Gunn's initial post received.
Laura Haddock (Meredith Quill, Peter Quill's mother) also appeared in Captain America: The First Avenger (2011) as a fan of Captain America.

Olivia Jackson, the stunt woman for Nebula on the first movie, suffered traumatic brain injury, and a left arm injury, which led to an amputation, as well as multiple fractures to the left side of her face, which required reconstructive surgery.

When the character of Ayesha was first introduced in the comics, she was just named "Her" (since she was created as a counterpart to the character Adam Warlock, originally named "Him"). She then took on the name "Kismet,"and then was renamed yet again as "Ayesha." In "Fantastic Four" #11 (by Chris Claremont, Salvador Larroca and Art Thibert) the Four ask her for her name, and she replies: "I have had many, but the most appropriate is Ayesha: She--who must be obeyed!" Both the name "Ayesha" and the sobriquet "She who must be obeyed" are references to the 1880s adventure novel She: A History of Adventure by H. Rider Haggard. The main character of the story was also a priestess named Ayesha (also referred to throughout as "She-who-must-be-obeyed"). The elaborate Art Deco-style costume and production design for this movie's Ayesha is also a nod to the most famous movie adaptation of Haggard's novel, She (1935).

Stan Lee's cameo refers to him being a postman, a potential reference to his cameo in Captain America: Civil War (2016). The events in that film, however, take place in 2016. Alternatively, this may be a reference to his cameo in Fantastic Four (2005), where he played the Baxter Building's mailman, Willie Lumpkin.
