It isn’t out of the ordinary for actors to immerse themselves in their roles before filming, but some are harder than others. Going “method” is a little harder to do when you’re supposed to be Spider-Man, though.
Tom Holland portrays Spider-Man in the most recent movie version of the character, but he is a British teenager. In order to get himself acclimated, the relative unknown actor thought it would be a good idea to go to a New York high school to get a sense of the American life. Marvel unexpectedly sent him to a school of science in the Bronx.
Poor Tom Holland couldn’t even get recognized in a high school before portraying Spider-Man!
