There is something particularly fascinating about watching an actress grow from a young television star into an even more compelling performer with age. Keri Russell turned 50 in March 2026, stars in the fourth season of one of Netflix’s biggest hits, The Diplomat, and has never seemed more comfortable in her own skin. More importantly, she has never looked like she was having so much fun.

To understand how she got here, we need to return to 1998, when a young woman with curly hair crossed the United States to follow a boy she had fallen in love with.

Felicity, created by J. J. Abrams and Matt Reeves, made Russell a television sensation. Her character was romantic, insecure, impulsive, and frequently wrong. Like so many young women, Felicity believed she was choosing her future when she was really beginning to discover who she was. Russell won a Golden Globe for the performance, but also learned an uncomfortable lesson: when she cut her famous curls, the decision sparked a national controversy. Audiences seemed to believe they had some ownership over the young actress’s appearance.

In 2007, Russell starred in Waitress, an independent film written and directed by Adrienne Shelly. Jenna was a woman trapped in an abusive marriage, facing an unwanted pregnancy and desperately searching for a way out through her remarkable talent for baking pies. Balancing humor and melancholy, Russell created a character who was neither a passive victim nor a conventional heroine. Shelly’s tragic murder before the film’s release added a painful dimension to a story that would eventually inspire a successful Broadway musical.

Then came Elizabeth Jennings.

In The Americans (2013–2018), Russell played a Soviet spy living undercover in the United States, torn between motherhood, marriage, and ideological loyalty. Elizabeth could be loving and terrifyingly cold, sometimes within the same sequence. She was a complex, frequently unpleasant character, and Russell never tried to make her more likable. Her ability to communicate inner conflict with a single glance established her as one of television’s finest dramatic actresses.

And then came Kate Wyler.

In The Diplomat, Russell seems to bring together everything she has learned, adding something that has not always received enough recognition: her extraordinary gift for comedy.

Kate is an experienced diplomat, supposedly prepared to handle international crises, negotiate conflicts, and navigate the subtleties of political relationships. At least in theory. Since becoming the American ambassador to the United Kingdom, her life has turned into an almost unbelievable succession of attacks, conspiracies, betrayals, and power struggles.

As I have already observed in my coverage of the fourth season, the series often seems more interested in explosions than actual diplomacy. But that hardly diminishes the pleasure of watching Russell try to manage the chaos.

Because Kate is not a woman who has everything under control. She is a woman who tries to control everything, rarely succeeds, and frequently makes matters worse.

And Russell seems to enjoy every second of it.

There is remarkable precision in her performance. Kate’s body always seems to move faster than her thoughts. She walks quickly, gestures, interrupts, reacts indignantly, and turns diplomatic conversations into personal battles. It is sophisticated physical comedy, performed by an actress who also knows exactly when to abandon the humor.

When Kate feels betrayed or emotionally exposed, Russell shifts gears in seconds. The woman who was making us laugh suddenly reveals genuine vulnerability, often returning to irony before the scene is even over.

Her chemistry with Rufus Sewell, who plays Hal Wyler, is another major strength. Their marriage is practically a war within a war. Hal is brilliant, charming, manipulative, and incapable of resisting the temptation to interfere in his wife’s career. Kate loves him, admires him, distrusts him, and frequently looks as though she would happily strangle him. Together, the actors turn their relationship into an irresistible combination of marital drama, comedy, and political warfare.

In the fourth season, Kate’s confrontation with Grace Penn, played by the extraordinary Allison Janney, opens up even more possibilities. Two intelligent, ambitious, powerful women, portrayed by actresses who master silence, irony, and indignation. Every encounter becomes an acting duel.

Kate is not necessarily a good diplomat. In fact, she is frequently a rather questionable one. But Russell never attempts to correct her flaws. Instead, she embraces every single one.

At 50, she no longer needs to make her protagonist likable or exemplary. She can allow Kate to be ridiculous, jealous, competent, passionate, unpleasant, and brilliant. There is a freedom in that choice that Hollywood has not always offered mature actresses.

Felicity was trying to discover who she was. Jenna was struggling to regain control of her life. Elizabeth placed a cause above her own happiness. Kate wants to manage her career, marriage, international politics, and emotions, even as everything threatens to explode.

And perhaps that is one of the most enjoyable things about growing older: discovering that maturity does not mean having all the answers.

Felicity captured a generation. Elizabeth Jennings revealed a great dramatic actress. But Kate Wyler allows Keri Russell to do everything at once. And at 50, she is finally soaring.
