It breaks my heart that this will never happen.
I think Andrew Garfield is a charming guy and a good actor, but I really can't justify doing a reboot so close to the old movies unless you're going to do something REALLY different, and I think Donald Glover would have brought that to the Peter Parker character. I've had enough of gritty reboots- I want a charming, funny Peter Parker who can't stop spewing cheesy lines at his villains. And yeah, he's a comedian so that's how I end up imagining it, but Donald Glover is a really talented guy and I'm sure he'd be more than capable of acting in a gritty reboot too.
IMO his personal transformation from nerdy kid in the suburbs to famous comedian/actor/writer/rapper mirrors Spiderman's own growth as a nerd into his new identity as a super hero. He was the perfect choice.
There were a lot of online debates that somehow it's racist to cast a black actor in a "white role". Bullshit. Hollywood is CONSTANTLY casting white people in roles for other races. (Just google "Racebending") The beautiful thing about a costume like Spiderman's as opposed to Batman or Superman- to any of the bystanders who wouldn't know Spiderman's secret identity, he really could be any race.
I think if they were trying to change an ethnicity of a more obscure character, sidekick, ect, no one would care.
This quote isn't entirely relevant to the debate (it's about book covers), but I thought it was an intelligent angle-
"But please consider that 'what sells’ or 'doesn’t sell’ can be a self-fulfilling prophecy. If black kids, Hispanics, Indians both Eastern and Western, don’t buy fantasy—which they mostly don’t—could it be because they never see themselves on the cover?” -Ursula Le Guin
