Tom Holland has already debuted as Spider-Man in Captain America: Civil War, and he has hopes of playing the character for many more years.
Holland may be done with his first solo outing, but has continued to bring Peter Parker to life by filming scenes for Avengers: Infinity War.
For the purposes of the Marvel Cinematic Universe, Peter is a 15/16 year old sophomore in high school, but Holland is just a few weeks away from being 21.
It would be really cool if it pans out, because it means I would be Spider-Man for a very long time.
