Trivia tropes for the comics:
- Crack Is Cheaper: A direct market copy of the first issue is unusually pricey, currently valued at nearly $200. That's much cheaper than, say, Action Comics #1 or Detective Comics #27 (which will cost you hundreds of thousands of dollars, if not millions), but those comics are many decades old, whereas USM #1 is only from 2000.
- Fandom Nod: In Ultimate Comics Spider-Man, after much fan complaint over the way Lafuente drew Peter's hair, Bendis decided to write up a scene with Mary Jane, Kitty, and Gwen forcing Peter to get a haircut, using several arguments fans used to bash his hairstyle.
- What Could Have Been: Spider-Man: The New Animated Series was originally going to be an adaptation of this comic series. Instead, it was changed into being a sort of follow-up to the first live-action film.
- Spider-Men, the first crossover between Ultimate Marvel and the 616 Universe, actually wasn't conceptualized as a crossover at first. The real purpose was actually meant to introduce the official 616!Miles Morales, who would go on to become a supporting character in Peter's title.
- Peter Parker was also meant to be one of the many deaths in Ultimatum. Bendis decided at the last second that he didn't want the character to die yet because he wanted to tell more stories with him. It was during the writing of of the relaunched book, Ultimate Comics Spider-Man, that Bendis would conceptualize Peter's Legacy Hero, Miles Morales.
- Word of God: After being asked if the comics would show what happened to [the resurrected] Peter Parker and his happy ending with Mary Jane, an editor stated that Ultimate Peter has been dead and gone for a long time, raising questions of Retcon and Canon Discontinuity.

- Relationship Voice Actor: Mary Jane and Silver Sable are Clover and Sam.
