I have it on good authority that Sir Ian McKellen is not a wizard. You have to understand, he can’t do magic. He only pretends to be a wizard. He stands where the director tells him to stand. He says what the script says he should say. He only pretends to be a wizard.
Similarly, I believe Gal Gadot intends only to pretend that she is Cleopatra. She is simply going to say what the script tells her to say. She will stand where the director tells her to stand. She will only pretend to be Cleopatra, but she won’t actually be Cleopatra.
