SPOILER WARNING: The following article contains spoilers for Spider-Man: Homecoming, in theaters now.

Sony might be getting all the box-office takings from Spider-Man: Homecoming, but Tom Holland's first solo(-ish) outing as the webbed wall-crawller is 100% the product of Marvel's Cinematic Universe -- and apart from Tony Stark's guest star role and the Captain America fitness videos, there are plenty of Marvel-ous Easter eggs peppered throughout the film to prove it.

Perhaps the most interesting of these comes in the form of Mr. Morita (Kenneth Choi), the principal at Peter Parker's high school. Choi also played Private Jim Morita in Captain America: The First Avenger. Private Morita served as one of Cap's Howling Commandos in the film, but was subsequently revealed to have died at some point between his World War II escapades and the time of the initial Avengers movie.

Eagle-eyed fans will be able to spot a black-and-white photo of Private Morita in Principal Morita's office, just as he is explaining to Peter the importance of keeping his academic career on track. The clear implication is that the principal is some kind of family relative, possibly even the son, of the Jim Morita we met in the first Captain America movie.

Fans should also keep an eye out for a pic of Bruce Banner in Peter's science class, a possible reminder of the man behind the Green Goliath ahead of his guest role in Thor: Ragnarok later this year.
