Spider-Man: Into the Spider-Verse

Art directors Dean Gordon and Patrick O'Keefe and their team turned to Cubism to help represent the dimensional quakes. Cubist art often presents a collection of different views all happening at the same time, so it was a natural metaphor for the multiple universes converging in "Spider-Verse."

Miles is nearly a foot shorter than Peter Parker, yet when Miles takes one of Peter's old costumes to use as his own, it fits him perfectly. This was done intentionally by the filmmakers, meant to be an illustration of Miles' earlier conversation with Stan, the comic shop owner ("It always fits. Eventually."). Miles has grown more confident, more skillful, and more comfortable with his new powers and is finally ready to take on the role of Spider-Man; thus the costume (like the role itself) finally "fits".

There is a dedication in the closing credits to "Spider-Man" creators Stan Lee and Steve Ditko, who passed away in 2018.

It is an image of Stan Lee's glasses with a quote: "That person who helps others simply because it should or must be done, and because it is the right thing to do, is indeed without a doubt, a real superhero. - Stan Lee" "Thank you Stan Lee & Steve Ditko for telling us we're not the only ones."

The Blu-Ray for the film features an "Alternate Universe Cut," featuring unseen, unfinished and unused footage, which shows alternate scenarios for certain scenes and extends the runtime to 2h 23m instead of the original 1h 57m.
