All four of the Tom Holland "Spider-Man" films have brought out Marvel Cinematic Universe guest stars to support Spidey. There was Iron Man (Robert Downey Jr.) in "Spider-Man: Homecoming," Nick Fury (Samuel L. Jackson) in "Spider-Man: Far From Home," and Doctor Strange (Benedict Cumberbatch) alongside many characters from older "Spider-Man" movies in "Spider-Man: No Way Home." "Spider-Man: Brand New Day" continues the trend, weaving a narrative that's built around different, converging corners of the Marvel Universe. Each supporting turn or cameo from another Marvel character is about serving this story, and they come with real dramatic weight. Not even leaning on other Marvel movies for major chunks of its story subtracts from that assessment.
