I just finished auditions for our school's production of Aida, and I am considering a female presenting actress for the role of Zoser. However, they are pangender and they use any pronouns. Would I be in trouble with MTI if I did cast them? They are really talented, and their rendition of "Another Pyramid" was just amazing. Would be a shame if I had to cast a male and not them. Just to make it clear, I AM NOT changing the gender of the character Zoser, just wanted to know if the actor had to be strictly a male. Thank you!
