Janet McTeer is reportedly in talks to take over from the late Dame Maggie Smith as Professor McGonagall in HBO's new Harry Potter series

Janet McTeer is reportedly being eyed to play Professor McGonagall in the Harry Potter remake, but how would her character compare to Maggie Smith’s?

Janet is only a couple of years younger than the late Maggie Smith was when she was cast as the Deputy Headmistress in the film franchise. In the Fantastic Beasts prequel films, the role was played by Fiona Glascott.
