Tom Holland went undercover at a top high school in America for the Spider-Man role.
Didn't know what "homecoming" was but pretended to be a student.
Sent to Bronx School of Science, one of the top-ranked high schools in the country.
Even teachers didn't know he was an actor and had to answer questions he didn't know.
Joked about the idea with Marvel, but they took it seriously.
Holland found school daunting, and it was filled with genius kids.
Shared a funny experience of telling a girl in the class he's Spider-Man.
The girl didn't believe him, thinking he was "nuts."
The experience helped him play high school scenes authentically, and praised for his role.
