Review: Rachel McAdams Contends with Reality in 'Mary Jane'
Making her impressive Broadway debut as the title character in 'Mary Jane,' Rachel McAdams offers a layered depiction of navigating a parenting nightmare.

"That tonal balance is delicate, and it could tilt in any number of directions: too grim and it might be impossible to watch (I would understand someone not wanting to engage with the premise), too woo-woo and it might become sentimental. It asks a lot, specifically, of the actress playing Mary Jane. Rachel McAdams turns out to be more than up for the task. She’s making her Broadway debut (if you vaguely recall her as a Canadian Shakespearean, you’re probably thinking of Slings & Arrows), but as she often does onscreen, McAdams works in ways that tend toward the understated, yet precisely observed. Crucially, she and Kauffman don’t treat Mary Jane as too much of a saint; in fact, she plays the part as someone who’s well-meaning but a flibbertigibbet. (A contrast to the 2017 Off Broadway version with Carrie Coon, who has an essential core of steel.)
Early on, I wondered if McAdams had fallen into the classic movie-actor trap of going too big once you get into a theater, but she used that energy to calibrate the character. In the first half, Mary Jane keeps making ill-timed half-jokes, which McAdams delivers with “Look at me” neediness. As Alex’s condition worsens, however, McAdams layers more anger and frustration into those jokes; her pointed, sometimes relentless niceness is more visible as a coping mechanism. Through that choice, I could see Mary Jane more clearly as a person, not just an archetype living through an experience. McAdams’s take helps draw out the arc underneath the surface of Herzog’s chain of one-on-one conversations. I was struck, at the end of the play, by her haunted stillness."
