In an interview with Rolling Stone, Spider-Man: Across the Spider-Verse writers and producers Phil Lord and Chris Miller were asked about Marvel Studios president Kevin Feige's involvement in the creative process of the film.
Specifically, the pair was questioned about the line delivered by Oscar Isaac's Miguel O'Hara when he referenced Tom Holland's Peter Parker and Benedict Cumberbatch's Doctor Strange.
"Marvel has given us a lot of rope. It’s been a very fruitful collaboration. But it’s not like there’s some shadowy board of figures that you have to run things by. I think Kevin’s a big admirer of the first movie and just believes like a rising tide lifts all boats. Like, 'These movies are cool, and it makes those movies cool. And we make each other cool.'"
