Continuity mistake: GUN was formed during the events of Sonic the Hedgehog 2. In the Knuckles series, the Buyer stated that GUN had existed long ago, under a different name. However, in the flashback in Sonic 3, the door of the laboratory that Shadow was in has the GUN logo.
Sonic the Hedgehog 3 (2024)
Directed by: Jeff Fowler
Starring: Idris Elba, Ben Schwartz, Colleen O'Shaughnessey
Trivia: Following the release of "Sonic the Hedgehog 2", co-star Jim Carrey stated that he was considering retiring from acting, as he felt he had "done enough" in the film industry and was becoming somewhat burned out. However, he eventually agreed to star in this film because he loves playing the evil-genius Dr. Robotnik. Carrey also laughingly admitted that the huge paycheck he got was one of the deciding factors, especially because he "buys a lot of stuff."
Trivia: Director Jeff Fowler, who directed all three "Sonic the Hedgehog" movies, actually worked on the game "Shadow the Hedgehog" as an animation director. Given his past with the character, he was excited and honoured to be the one who got to introduce Shadow on the big screen.
Trivia: When Jim Carrey announced he was considering retiring from acting, he jokingly said he would consider returning to act if "angels" delivered a script "written in gold ink." In order to get Carrey back for this film, director Jeff Fowler had a copy of the script made that was printed in actual 24 karat golden ink to show how serious he was about the movie and the character.
Sonic the Hedgehog: What did you do?
Shadow the Hedgehog: What I had to!
Shadow the Hedgehog: When we're done, there won't be anything left.
Sonic the Hedgehog: Hey, no cheat code!
Question: SPOILERS: When Sonic and Shadow land on the moon, they have a heart-to-heart conversation and appear to be breathing. But there's no air on the moon. Are we to assume that the Chaos Emeralds (which have given them both powers) are giving them the ability to breathe and speak in the environment?
Question: How did Stone see Robotnik's message at the end? It appeared to be displayed on jumbotron-like devices in big city squares, but Stone was in London and there didn't appear to be any giant screens, or even small ones, anywhere near him.
Answer: Per a quick Google search, it appears there are several locations in London where there are giant screens. He likely was running around the city in a panic (there is a doomsday weapon threatening to destroy mankind, after all) and managed to stumble onto one of the locations.
Answer: They still have the Chaos Emerald power at that point because, immediately after, they turn gold and fly away.
Honestly, that's probably the best answer.
