back in 2015 the final Spider-Man choice was between Asa Butterfield, Charlie Plummer, Matthew Lintz, and Tom Holland. we all know how it ended.
Asa's reflections on that:
"Every so often there’s a part [that you really want] and it’s a script you love, and you kind of put your heart and soul into it, and you don’t get it. And it is tough and it is shit, but I often find that something even better comes out of it at the end. And so in the case of Spider-Man, I did Sex Ed, because I wouldn’t have been able to do both of those at the same time."
"Tom did amazing things with Peter and he had an entirely different portrayal of him, and I think it’s worked so well in the universe and in that part, and I don’t think I could do it. So I think all things work out in the end."
