I actually find quite amusing that people want Cillian as Voldemort, since he is one of the most or the most popular fancast for Alphard Black, Sirius's uncle...

Apparently, the most rumored choice for Voldemort’s role is Cynthia Erivo. I don’t really believe it, but since Snape is black and the audition for Voldemort reportedly welcomes people of any gender, I guess it’s as much a possibility as Cillian Murphy was.

The one of wicked?!

As Voldemort? Ok, so yeah, it's nice to have casting diversity, but a female Voldemort...

Internet will go mad, I do hope its a good series though.

Internet will go mad

It has. The series has been said to follow the books accurately, and ironically (and unfortunately) it has been failing to do so so far.

I mean, I like the plan that they make series and films for diverse...

But, no offense, I would like a male r a non-binary to represent Voldemort, not a girl. If she does the work well or has a low voice, it could work. But what are they doing, honestly? If the character is a male, then it's a male.

Sigh. I will say this to any person who hates the Snape casting: just because you are black doesn't mean you are sallow of skin. This applies to any race. Also, they have been casting females to play Voldemort since in the books he has a really high voice, and some woman play men, like voicing in cartoons.

Not trying to pick a fight but, is the tv show gonna be a cartoon?

No
