Each time a new Doctor is discussed, the name of the famous pop star turned Companion comes up as a possibility. We’re not sure how this would would, probably something wibbley-wobbley and timey-wimey.
When fans suggested her as a replacement Doctor, Mirren famously said, “I think it’s absolutely time for a female Doctor Who. I’m so sick of that man with his girl sidekick. I could name at least 10 wonderful British actresses who would absolutely kill in that role.”
However, since the role has traditionally gone to actors who previously did not have much face recognition, it seems unlikely that Dame Helen will be cast in the show.
