20 Things You Didn’t Know About Spider-Man: Into The Spider-Verse
12. Spider-Man: Into The Spider-Verse Uses Wolverine's SNIKT
Not only does the art-style of Spider-Man: Into the Spider-Verse resemble a comic story (with the Kirby dots and everything), onomatopoeic words like "BAM!" and "BOOM!" flash on-screen to accentuate the action sequences. (One of the coolest things to see was Spidey's web-swinging was accompanied with a visual "THWIP," which has been used in the comics for decades.)
One of the best usages of this technique occurs when The Prowler chases Miles in the subway. As Miles sticks to the ceiling, Prowler activates his claws, while the word, "SNIKT" momentarily appears in the background. If you're well-versed in Marvel lore, you should recognise "SNIKT" is the sound used in comics when Wolverine pops his adamantium claws.
This moment lasts less than a second, but it's a great nod to one of Marvel's most beloved superheroes.
