 Norton followed up by inquiring as to if she was still in contact with "the young performers."

Many ardent Harry Potter fans have expressed great dismay at the controversy.

 Emma Watson also made it known on Twitter that she disagreed with Rowling.

Rowling produced a 3,700 word article to defend her views after receiving criticism.

Rowling's staff informed EW days before the HBO Max special aired that the author declined to take part.

 Rowling appeared in archival material for the reunion show.
