It’s been decades. People still talk about the diner scene. They still argue about whether men and women can truly be "just friends" without the sex part getting in the way. But when you look back at who starred in When Harry Met Sally, you realize the movie’s staying power isn't just about Nora Ephron’s sharp-as-a-tack script or Rob Reiner’s direction. It’s about the specific, weirdly perfect alchemy of a cast that almost didn't happen.
Billy Crystal and Meg Ryan. That’s the short answer. But the long answer is way more interesting because, honestly, neither of them was the first choice. Not even close.
The Leading Man Who Almost Wasn't Harry
Billy Crystal wasn't a movie star in 1989. Not really. He was a comedian, an SNL alum, a guy people knew from The Princess Bride for a few minutes of screen time as Miracle Max. Rob Reiner actually looked at a lot of people for Harry Burns. We’re talking heavy hitters. Tom Hanks was offered the role but turned it down because he thought the movie was too "light." Imagine that. Albert Brooks also said no.
Crystal got the part because he was Reiner's best friend in real life. They’d sit around talking about their own experiences with divorce and dating, and those late-night vent sessions basically became the foundation of Harry’s cynical, spitfire personality. Crystal brought something specific: a neurotic, fast-talking New York energy that felt lived-in. He wasn't just playing a character; he was playing a version of the guy he was when he was hanging out with Reiner.
The chemistry worked because it was built on actual history. When Harry tells Sally that "when you realize you want to spend the rest of your life with somebody, you want the rest of your life to start as soon as possible," it doesn't sound like a canned movie line. It sounds like a guy who finally stopped running from his own shadow.
Sally Albright and the Meg Ryan Revolution
If you're asking who starred in When Harry Met Sally, you’re really asking how Meg Ryan became the "Queen of Rom-Coms." Before 1989, she was mostly known for Top Gun and some soap opera work. She wasn't the first pick for Sally either. Molly Ringwald was the frontrunner. Can you picture that? The Pretty in Pink star bringing that John Hughes angst to a New York intellectual comedy? It would have been a totally different movie.

Ryan won the role because she wasn't afraid to look a little ridiculous. The famous Katz’s Delicatessen scene—the one where she fakes an orgasm in the middle of lunch—was actually her idea. Reiner was explaining the concept, and Ryan basically said, "I should just do it. Right here."
That’s the thing about Sally. She’s high-maintenance, sure. She wants her salad dressing on the side. She wants her pie heated but the ice cream not on the pie, but next to it. But Ryan played her with such a grounded, sunlit warmth that you totally understood why Harry fell for her over the course of twelve years. She made neuroticism look charming rather than exhausting.
The Supporting Cast: Carrie Fisher and Bruno Kirby
You can’t talk about the leads without mentioning the best friends. Honestly, Marie and Jess are the secret sauce of this film.
Carrie Fisher, fresh off a decade of being Princess Leia, showed up as Marie with a Rolodex full of eligible bachelors and a dry, cynical wit that balanced Sally’s optimism. She’s the one who tells Sally, "The right man for you might be out there right now and if you don't grab him, someone else will, and you'll have to spend the rest of your life knowing that someone else is married to your husband." It’s dark. It’s funny. It’s very Carrie Fisher.
Then there’s Bruno Kirby as Jess. Kirby and Crystal were friends in real life too, and you can see it in their banter. They have this rhythm that you can't fake in a table read. When Jess and Marie end up together—the two "rejected" friends finding love with each other—it serves as the perfect foil to Harry and Sally’s endless "will-they-won't-they" drama.

Other Notable Faces
- Steven Ford: He played Joe, Sally’s boyfriend who she eventually breaks up with. Fun fact: he’s the son of former President Gerald Ford.
- Michelle Nicastro: She played Amanda, the girl Harry is seeing at the beginning who sets the whole plot in motion during that long drive from Chicago to New York.
- Harley Jane Kozak: She played Helen, Harry’s ex-wife. Her presence looms large over the first half of the movie as Harry struggles to get over their divorce.
- Estelle Reiner: Rob Reiner’s mother. She’s the woman at the table next to Sally in the diner who delivers the most famous line in cinema history: "I'll have what she's having."
Why the Casting Worked (The E-E-A-T Perspective)
Film critics like Roger Ebert and Gene Siskel pointed out at the time that the movie succeeded because it felt like a Woody Allen film but without the crushing weight of existential dread. It was accessible.
The casting directors, Jane Jenkins and Janet Hirshenson, were masters at finding people who felt like "real people" you’d meet at a bookstore or a New Year's Eve party. They didn't go for the most glamorous stars of the 80s; they went for actors who could handle Ephron’s rapid-fire dialogue. If you listen to the way Harry and Sally talk, they overlap. They interrupt. They mumble. It’s a very specific style of acting that requires a lot of trust between the performers.
Crystal and Ryan spent weeks improvising before cameras even rolled. This allowed them to develop "bits" that felt organic. The scene where they’re talking on the phone while watching Casablanca in their respective beds? That wasn't just clever editing. They actually filmed those parts simultaneously to keep the timing tight.
The Real People Interspersed Throughout
A detail people often forget when looking at who starred in When Harry Met Sally is the documentary-style interludes. Throughout the movie, we see elderly couples telling the stories of how they met.
These weren't actors playing random characters. Well, they were actors, but the stories they were telling were 100% real. Nora Ephron interviewed dozens of real-life couples and then had actors recreate those interviews. It adds a layer of authenticity to the film. It reminds the audience that while Harry and Sally’s story is scripted, the messy, complicated, and often accidental nature of love is very real.

The Legacy of the Harry and Sally Archetype
Because of the performances by Crystal and Ryan, we now have a "type." Every rom-com for the next twenty years tried to replicate this. The "grumpy/sunshine" trope? Harry and Sally did it best. The "friends-to-lovers" slow burn? They set the gold standard.
If Tom Hanks had played Harry, the movie probably would have been a massive hit, but it would have been "softer." Hanks has a natural likability that makes it hard to believe he’s a cynical jerk. Crystal, however, has a bit of an edge. You believe him when he’s being a pessimistic New Yorker. That edge makes the eventual payoff—the New Year’s Eve confession—hit so much harder.
Actionable Takeaways for Movie Buffs
If you're revisiting the film or studying it for the first time, keep an eye on these specific performance details:
- Watch the background during the museum scene. The way Crystal and Ryan move together—the physical comedy of the "peculiar" voice Harry uses—is entirely improvised. It shows how comfortable they were with each other.
- Listen to the cadence. The film is basically a play. Notice how the actors use silence. In the scene where they finally sleep together, the awkwardness is palpable because of the lack of dialogue.
- Notice the wardrobe. Sally’s outfits (the power blazers, the high-waisted trousers) became iconic because they reflected her "ordered" personality. Harry’s white chunky knit sweater? Total contrast.
The movie works because the cast understood that the story wasn't just about a romance. It was about two people growing up. We watch them go from being annoying twenty-somethings to somewhat-functional adults over the course of 96 minutes. That’s a testament to the actors’ ability to age their characters internally, not just with different hair and makeup.
To truly appreciate the film, look for the 30th-anniversary interviews featuring Reiner, Crystal, and Ryan. They discuss how their real-life friendships informed the script, specifically how the "men and women can't be friends" debate was a constant argument on set. Knowing the friction behind the scenes makes the on-screen chemistry feel even more impressive.
