I would like to address the review by "lukemanning from London" who probably thinks every American accent is a valley girl accent. As a Canadian, our accent is very close to the American accent, so I feel pretty qualified to say that Catherine Steadman's American accent was very good, I didn't realize she wasn't American. Very good for a modern American accent that is, I wouldn't know whether this was accurate for early 20th-century America.
I am originally Egyptian (Egyptian who grew up in Canada) and I have been looking into the actors of the Egyptian characters in Tutankhamun and I have been quite disappointed. Only one of them (Selim) seems to have Egyptian origins, but even he is actually ethnically mixed and doesn't look completely Egyptian, and his Arabic accent wasn't great. The rest didn't seem to be Egyptian. Egyptian cinema is booming, there is no shortage of Egyptian actors, and all Egyptians learn English in school, so there really is no reason why they couldn't have used Egyptian actors rather than British actors who look like they could pass for Egyptians. The Egyptian economy definitely needs all the help it can get right now, so it feels a little bit of an affront that they would make a movie set in Egypt and benefit off Egyptian history, and yet choose the filming and the Egyptian characters to have nothing at all to do with Egypt, thereby avoiding benefiting Egypt in any way.
I am enjoying the show and find it entertaining, but I am disappointed with how it was not Egyptian in any way. I hope that this show at least makes people more interested in visiting Egypt and brings back some of the tourism that has died in the last few years.
