If there's one thing superfans love, it's inventing shared universes.
ET spoke to Holland at a screening of the film in New York City on Monday, where he dished on meeting both Tobey Maguire - who played Spider-Man in Sam Raimi's trilogy, which kicked off in 2002 - and Andrew Garfield, who took over the character in the 2012 reboot, The Amazing Spider-Man.
Turns out that Marvel producers didn't always plan for Peter Parker to make his MCU debut in Iron Man 2. There's the theory that all the Pixar movies are in the same universe and a more or less confirmed theory that every Quentin Tarantino movie is in the same universe. In particular, Donald Glover's role, which clearly indicates that Miles Morales exists in the same universe as Peter Parker, since he will be the uncle of the second Spider-Man.
Spider-Man: Homecoming releases on July 7.
"I can confirm that as of today", Holland said.
That courageous kid is, in fact, Peter Parker.
"I remember watching that with [Marvel Studios head] Kevin Feige and everyone and being like, 'Does the math work on that?'" Watts recalled. Just kind of making a distinct character, making somebody that I think is different and embracing the weird. He said: "There's a pretty big crew already in those movies, but you might keep an eye out. [But] yeah I think I'm signed for two movies".
As the longest-serving member of the Marvel Cinematic Universe - RDJ first declared that he was, in fact, Iron Man all the way back in 2008 - it's nearly hard to imagine a future in which Robert Downey Jr.'s version of Tony Stark is no longer needed within the MCU.
