It’s the ingénue performers, the newbies, and the surprise turns that gave us hope for the future of screen storytelling in 2023. Especially in a marketplace — ew — driven by repeats, volume, and content-feeding, the unexpected can hit with a sharper shock than ever nowadays in theaters and on TV.

In the last year, we’ve seen some known or known-enough actors deliver unpredictable, accomplished work, along with fresh faces out of the clear blue that took us aback or pulled us in with their acting debuts. What is a breakthrough performance? We’ve turned that definition over and over to round up performances that stood out from the content morass, that broke through their stories to elevate and transcend the film or series around them. Or to sharpen its point in yet another year of innumerable offerings.

Some of these shows or movies didn’t quite reach the audience they should have, while others did but were perhaps outshone by buzzier peers (despite equally solid performances). Others stood out in genres often underappreciated in the bracket of the quote-unquote best movies and TV of the year. These performances mattered to us in 2023, and will matter in the coming years upon revisits, and will matter even more when we can say, “This is what put them on the map.” (Here’s last year’s list, just to see how they stacked up.)

Below, in an unranked order, are our picks for the 20 breakout performances of the year.
