It was 1998. Bill Clinton was in the news for all the wrong reasons, everyone was terrified of the Y2K bug, and a show about a gay lawyer and his straight interior designer best friend premiered on NBC. People forget how risky that felt. Seriously. Before the cast of Will and Grace became household names, the idea of a prime-time sitcom centered on gay characters was considered a massive gamble by "Must See TV" executives.
Fast forward a couple of decades. The show didn't just survive; it reshaped how we talk about identity, friendship, and the concept of "chosen family." But here’s the thing: the magic wasn't just in the writing by Max Mutchnick and David Kohan. It was the four-headed monster of a cast. Eric McCormack, Debra Messing, Sean Hayes, and Megan Mullally had a chemistry so specific and so combustible that it basically ruined the sitcom genre for everyone else. They made it look too easy.

The Anchors: Eric McCormack and Debra Messing
When you talk about the cast of Will and Grace, you have to start with the title characters, obviously. Eric McCormack wasn't actually the first choice for Will Truman—the producers looked at hundreds of actors. McCormack, a Canadian theater veteran, brought a grounded, almost "straight-man" (ironically) energy to the role of a neurotic, high-strung lawyer. He was the "will" of the show. Pun intended. He had to be the adult in the room while everyone else was bouncing off the walls.
Debra Messing was the secret weapon. She had this Lucille Ball-esque physicality that you just don't see much anymore. Grace Adler was messy. She was food-obsessed, unlucky in love, and incredibly stylish yet constantly disheveled. Messing didn't care about looking pretty on screen; she cared about the joke.
Think about the "water bra" episode. Or the time she got stuck in the shower. Her ability to pivot from a heartfelt moment about her Jewish heritage to a full-blown slapstick routine is why she won that Emmy in 2003. They were the heart. Without them, the show would have been a collection of mean-spirited quips. With them, it was a story about two people who were soulmates, just not in the way society expected.
The Chaos Agents: Sean Hayes and Megan Mullally
Let’s be real. Jack McFarland and Karen Walker stole the show. Frequently.
Sean Hayes was a virtual unknown when he was cast as Jack. He was actually on a music scholarship and worked as a musical director before hitting it big. His performance as Jack was revolutionary. Before "Just Jack," gay characters on TV were often tragic or saintly. Jack was neither. He was narcissistic, flighty, obsessed with Cher, and absolutely hilarious. He gave us the "slap-fight." He gave us the "side-eye." He was the first person many Americans "knew" who was unapologetically, loudly gay.
Then there’s Megan Mullally.
Karen Walker shouldn't have worked. A pill-popping, martini-swigging socialite who treats her maid like a frenemy? On paper, she’s a villain. But Mullally did something brilliant. She gave Karen a high-pitched, squeaky voice (which wasn't in the original pilot, by the way) and a hidden vulnerability. Her relationship with Rosario—played by the late, great Shelley Morrison—was arguably the most complex "friendship" on the show.
The cast of Will and Grace functioned like a jazz quartet. Will and Grace provided the melody. Jack and Karen provided the wild, improvisational solos that kept you on the edge of your seat. If you watch those early seasons now, the timing is breathless. They finish each other’s sentences with a precision that usually takes decades to develop.
Why the Revival Actually Worked (and Why It Ended)
In 2017, the world was weird again. So, the cast of Will and Grace came back.
Usually, TV revivals are a disaster. They feel like a desperate cash grab or a sad high school reunion. But the eleven-year gap seemed to have sharpened them. They ignored the series finale of the original run—where Will and Grace hadn't spoken for twenty years—and just pretended it never happened. Honestly? Good call.
The revival tackled the Trump era, aging, and the changing landscape of LGBTQ+ rights. It reminded us that these characters weren't static. Will wanted to be a father. Grace was dealing with the loss of her mother (a beautiful tribute to the late Debbie Reynolds, who played Bobbi Adler).

However, rumors of friction on set during the final season of the revival circulated. Fans noticed Debra Messing and Megan Mullally stopped following each other on social media. It was a reminder that even the most legendary casts are human. They grew up. They changed. And after 11 seasons across two decades, the curtain finally came down for good in 2020.
The Supporting Players You Forgot
You can't talk about the cast of Will and Grace without mentioning the recurring guests. This show was a magnet for A-listers.
- Leslie Jordan as Beverly Leslie: The pint-sized rival to Karen. Their "intersexual" banter was comedy gold.
- Harry Connick Jr. as Leo Markus: The man who finally got Grace to the altar.
- Bobby Cannavale as Vince D'Angelo: Will's first truly serious boyfriend.
- Minnie Driver as Lorraine Finster: Karen's stepdaughter and ultimate nemesis.
The Legacy of the Core Four
Joe Biden famously credited Will & Grace with doing more to educate the American public on LGBTQ+ issues than almost anything else. That’s a heavy lift for a sitcom about a guy who likes fancy towels and a woman who can't stop eating his snacks.
The cast of Will and Grace didn't just play characters; they became cultural touchstones. They proved that a show with "niche" characters could be a global juggernaut. They showed that friendship is just as valid a life-partnership as marriage.

If you’re looking to dive back into the series or explore what the actors are doing now, here are the best ways to engage with the legacy:
- Watch the "Live" Episodes: If you want to see the raw talent of this cast, watch the episodes they filmed live. Their ability to handle screw-ups and keep the energy high is a masterclass in acting.
- Listen to "SmartLess" and "Just Jack & Will": Sean Hayes has pivoted into the podcasting world brilliantly. SmartLess is a global hit, but Just Jack & Will (co-hosted with Eric McCormack) gives a deep, episode-by-episode look at the show's history.
- Support Local Theater: Many members of the cast, especially McCormack and Mullally, are theater purists. Keep an eye on Broadway and West End listings; they frequently return to the stage.
- Track the Social Impact: Look into organizations like GLAAD, which the show has supported for decades. Understanding the political context of 1998 makes the humor hit even harder today.
The sitcom era of the late 90s is mostly gone, replaced by prestige dramas and 15-second TikToks. But the cast of Will and Grace remains a gold standard. They weren't just funny; they were necessary. They invited us into their living room, made us a drink, insulted our outfits, and made us feel like we belonged.
