Laura Harrier of the soap opera "One Life to Live" has been cast in a " significant role in Sony and Marvel’s “Spider-Man: Homecoming.”
Tony Revolori of the excellent Grand Budapest Hotel has been cast as "Peter Parker’s nemesis/enemy at high school." Allegedly it will be a character named Manuel.
If you add Zendaya as Michelle, it seems like they're going with an ethically diverse supporting cast (entirely appropriate for New York City now) and new characters (unless Manuel and Michelle are placeholder names.)
