There’s 1 Professor McGonagall Balance The Harry Potter Remake’s Actor Needs To Nail
The Character Must Have An Intimidating Side & A More Compassionate One
ManyHarry Pottercharacters can be broken down to one prominent trait, butMcGonagall has two distinct sides to her: the stern, strict Hogwarts professor and the kinder, more compassionate mentor. Part of the reason McGonagall is so lovable in the books is because she balances both of these personas well, bringing each of them out at exactly the right time.

Janet McTeer vs Maggie Smith: How HBO’s Rumored McGonagall Compares To The Harry Potter Movies
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?
Smith knew how to juggle both qualities on-screen, ensuring that theHarry Pottermovies' take on McGonagall fit with her book description — and that she landed well with viewers. Some of the star’s best moments as McGonagall involved well-timed jokes or heartfelt interactions with her students. However, when it came down to it, Smith’s take on the character could put up a fierce fight against Death Eaters, something she proved during the Battle of Hogwarts inHarry Potter and the Deathly Hallows.

Given that this balancing act is true to McGonagall’s character in theHarry Potterbooks, McTeer will need to master it just as well as Smith.

Helen Pierce & Hera Prepared Her To Play The Harry Potter Professor
McTeer has many great roles under her belt, but two of her recent TV series stand out ahead of her potentialHarry Pottercasting: Netflix’sOzark and Kaos.InOzark, McTeertook on the role of Helen Pierce, an accomplished lawyer who works for the Navarro drug cartel. As you might imagine, this position pushes her to be extremely competent and ruthless. She’s someone who can work with people like the Byrdes, but she’s also there to intimidate them.

Although both Helen Pierce and Hera are both more ruthless than McGonagall, the characters do prove that McTeer can be formidable.

McTeer’sKaosrole boasts similar energy to herOzarkone, as she plays Hera in Netflix’s one-season Greek mythology satire. Although she’s forced to deal with the whims and outbursts of Jeff Goldblum’s Zeus, Hera is fierce, commanding, and confident — all traits that McTeer’s McGonagall could benefit from.

McTeer even discussed this detail of the character withTheWrap, noting, “You need somebody who can look like they’re really scary and terrifying, but someone who can also be more complicated, softer, more motherly.”

While McGonagall shouldn’t necessarily be scary,itisimportant that McTeer can tackle her character’s more compassionate and nurturing moments. And the fact that she’s gone back and forth between the two extremes inJessica Jonesbodes well for her potentialHarry Pottercasting. After all, she’ll need to switch each side on and off depending on what McGonagall is doing and whom she’s interacting with. Although the Golden Trio is the central focus of the story, getting characters like McGonagall wrong could make or break the show.
