Diverse multicultural Doctor Whoke rejects Joe Hill because... he's american
Yeap, BBC's Doctor Whoke, these guys that have filled the series with Pakistanis and Africans, they rejected Joe Hill because... he's american.
The rejection letter said literally "We have never let an American write Doctor Who, and if we were going to, we wouldn’t start with you".
The 'we wouldn't start with you' obviously means 'if we give the job to somebody from US, he won't be a white male, as you are'
Joe Hill is the son of Stephen King. But this is not a case of a son wanting to enjoy the benefits of daddy (he even uses his mother's surname). He has been an horror writer for a while, and he has become quite a successful one. Netflix even released recently a series based in a comic book series written by him.
