Few actresses have had a better year than 22-year-old Kaitlyn Dever. In Booksmart, which debuted in May to rapturous reviews, Dever portrayed Amy, a bookish teenager seeking to prove to her classmates that nerds can party, too. In Unbelievable, out this month on Netflix, Dever plays Marie Adler, a resilient young woman who reports being raped at knifepoint, recants her story under police pressure, then sees herself slapped with an accusation of false reporting. Dever is sensitive and sensational as Marie, walking a masterful tightrope of confusion, rage, and trauma.
