10 Sitcom Characters Who Were Almost Played by Someone Else Entirely

Casting a sitcom is part science, part gut feeling, and part pure luck. For every iconic performance that feels like it was written in the stars, there’s a paper trail of near misses, turned-down offers, and last-minute swaps that could have completely changed the shows we grew up watching. Some actors walked away from roles that became career-defining for someone else, while other performers came agonizingly close before losing out in the final round.

Looking back at these casting stories now, it’s almost impossible to picture anyone but the actor who actually landed the part. Still, the alternate timeline is fascinating to think about, and it says a lot about how fragile the alchemy of a great ensemble cast really is.

1. Joey Tribbiani (Friends) – Almost Vince Vaughn

Long before he became a leading man in Hollywood comedies, Vince Vaughn walked into a room to audition for the role of Joey Tribbiani on Friends. Vince Vaughn initially auditioned for the role of Joey in Friends, a part now synonymous with Matt LeBlanc. He clearly left an impression, too.

According to casting director Ellie Kanner, Vince was “handsome and tall” and a “good actor,” but Matt ended up being a better fit for the part. It’s a reminder that talent alone doesn’t guarantee a role; sometimes it just comes down to chemistry with the rest of the cast and the specific tone a character needs.

2. Chandler Bing (Friends) – Almost Jon Favreau

Jon Favreau, who went on to direct blockbusters like Iron Man and The Jungle Book, was actually the producers’ pick to play Chandler Bing before Matthew Perry ever entered the picture. Jon Favreau came closer than anyone else besides Perry, since he was actually offered the role of Chandler Bing, but according to HBOMax’s Friends: The Reunion, he turned down the role.

Favreau didn’t disappear from the show entirely, though. He went on to later play Pete Becker, Monica Geller’s wealthy boyfriend, for a few episodes during the third season of Friends. It’s a strange bit of trivia: the man who almost played Chandler ended up dating Chandler’s future wife on screen instead.

3. Phoebe Buffay (Friends) – Almost Ellen DeGeneres

Before Lisa Kudrow brought her quirky warmth to Phoebe Buffay, the role was reportedly Ellen DeGeneres’s to lose. Ellen DeGeneres was actually the producers’ first choice to play Phoebe Buffay, and Ellen was the one who turned down the role, which later went to Lisa Kudrow.

It’s hard to imagine anyone else delivering Phoebe’s off-kilter songs and dreamy non-sequiturs the way Kudrow did for ten seasons. Still, DeGeneres’s comedic instincts might have taken the character in an entirely different direction, and it’s fun to wonder what a Phoebe built around her particular brand of humor would have looked like.

4. Ross Geller (Friends) – Almost Eric McCormack

Years before he became Will Truman on Will & Grace, Eric McCormack tried out repeatedly for the role of Ross Geller. Eric McCormack took multiple auditions for Ross but was passed over, which led him to eventually land a lead role in Will & Grace.

McCormack later learned just how close he’d come, and also how futile his effort had been from the start. The producer and director of the pilot, James Burrows, told him years later, “Honey, you were wasting your time. They wrote the part for Schwimmer.” Sometimes a role really is written with one specific actor in mind, no matter how many people read for it.

5. Jim Halpert (The Office) – Almost Adam Scott

Adam Scott, who would later become a comedy fixture on Parks and Recreation, was in the running to play Jim Halpert on The Office before John Krasinski made the role his own. Adam auditioned for the role of Jim, and you can watch his audition online.

Fans of both shows can probably agree it worked out for everyone in the end. It’s hard to imagine anyone but John Krasinski now, and Adam getting the role would have deprived audiences of him playing Ben Wyatt on Parks and Recreation. Scott’s near miss on The Office ended up freeing him for a role that felt just as tailor-made for him.

6. Sheldon Cooper (The Big Bang Theory) – Almost Johnny Galecki

Long before Jim Parsons turned Sheldon Cooper into one of the most recognizable characters on television, the role was actually offered to his eventual co-star. One co-star was actually initially poised to play the role: Johnny Galecki, who portrayed Leonard Hofstadter in the CBS sitcom.

Galecki asked to switch lanes instead, and the results speak for themselves. Once everyone who saw Jim Parsons audition for the character realized he understood Sheldon from day one, casting director Nikki Valko noted it wasn’t like he came in with a bow tie or looked stereotypically nerdy; he just got it. Even creator Chuck Lorre, who had a very different character in mind, was won over almost instantly.

7. Elaine Benes (Seinfeld) – Almost Rosie O’Donnell or Megan Mullally

Before Julia Louis-Dreyfus made Elaine Benes an icon of neurotic New York comedy, at least two other well-known comedians were in serious contention. Jerry Seinfeld confirmed that Rosie O’Donnell was up for the role of Elaine early in the show’s development, and although he thought she was funny, he didn’t think she was right for the part.

Megan Mullally, who later found her own iconic sitcom home, was also reportedly in the mix. Megan Mullally was a frontrunner for Elaine before Julia Louis-Dreyfus came in and knocked everyone’s socks off. Mullally, of course, went on to win acclaim playing Karen Walker on Will & Grace instead.

8. Cosmo Kramer (Seinfeld) – Almost Tony Shalhoub

Michael Richards’s rubbery physical comedy is so tied to Kramer that it’s genuinely startling to learn how close the role came to going to someone else. Before Michael Richards was cast to play Kramer, Tony Shalhoub was considered for the role.

The story gets even more interesting years later, when the two actors’ paths crossed again over a completely different show. Funnily enough, when Monk was in development, producers initially wanted Richards for the title role, but Richards didn’t like the script and instead opted for his own short-lived show, allowing Shalhoub a second career wind as Adrian Monk. Two actors, two iconic near misses, and both careers still worked out just fine.

9. Phil Dunphy (Modern Family) – Almost Matt LeBlanc

Five years removed from Friends, Matt LeBlanc had a shot at another beloved sitcom dad role, and he walked away from it. Five years after Friends ended, Matt LeBlanc was offered the role of Phil in Modern Family but turned it down, telling USA Today, “I remember reading it thinking, this is a really good script, but I’m not the guy for this.”

The role instead went to an actor who made it entirely his own. The role later went to Ty Burrell, who won two Emmy awards for his portrayal of the character. It’s a rare case where the actor who said no seemed genuinely at peace with his decision, recognizing early on that the part just wasn’t a fit for his instincts.

10. Robin Scherbatsky (How I Met Your Mother) – Almost Jennifer Love Hewitt

Before Cobie Smulders brought her sardonic charm to Robin Scherbatsky, Jennifer Love Hewitt was reportedly considered for the role. Before Cobie Smulders was cast, Jennifer Love Hewitt was considered for the role of Robin Scherbatsky in How I Met Your Mother.

Hewitt ultimately went in a different direction professionally, choosing a starring role elsewhere instead. The show’s creators, Craig Thomas and Carter Bays, revealed that Jennifer turned down Robin to play the lead role in Ghost Whisperer in 2005, the same year. Smulders stepped in and spent nine seasons turning Robin into one of the show’s most layered characters.

What ties all of these stories together is how thin the line really is between an actor becoming a household name and simply becoming a footnote in someone else’s casting history. A single audition, a scheduling conflict, or even a change of heart at the last minute was often enough to send an entirely different career down an entirely different path. It’s worth remembering the next time you rewatch one of these shows: the version you know and love was never guaranteed. It was just one possibility among several, and somehow, it turned out to be the right one.
