There are actors who disappear into roles, and then there’s Glenn Howerton, who disappears into Dennis Reynolds so completely that viewers still ask whether he’s secretly that unhinged. The confusion is a compliment — the verifiable record shows he co-created It’s Always Sunny with Rob McElhenney and Charlie Day and trained at Juilliard before he ever played television’s most confident narcissist.

Who played Dennis Reynolds?
Glenn Howerton played Dennis Reynolds on It’s Always Sunny in Philadelphia, and he’s played him from the first episode to the most recent season — the credit record leaves no gap (IMDb credit list). Dennis is the show’s self-appointed golden god: vain, controlling, and completely sure he’s the smartest person in any room. That combination made the character a fan favorite and the answer to the question this section is asking.
That distinction matters later. First, the cast questions that keep showing up in search results.
Was P. Diddy in It’s Always Sunny?
- No. There’s no record of P. Diddy in the show’s cast. The credited actors associated with It’s Always Sunny — the same records that list Howerton and the rest of the Gang — don’t include Combs (It’s Always Sunny cast list).
The idea spreads on fan pages, not in the series’ episode archives.
Did they replace Dee on It’s Always Sunny?
- No. Kaitlin Olson has played Dee Reynolds from the start of the aired series, and the show has never recast the role.
The role is Olson’s, and the Gang’s running joke about Dee being underappreciated doesn’t extend to the casting.
The implication: Dennis Reynolds is the role Howerton will be asked about for the rest of his career, but the confidence behind the character is performance training, not personality.
Is Glenn Howerton Juilliard trained?
Yes, and the timeline is well documented. The path was also unusually international: born in Japan to a military family, with childhood stops in England and South Korea before the family settled in Alabama — a biography that Apple TV’s actor profile lays out in detail. He attended Jefferson Davis High School in Montgomery, per his Us Weekly celebrity profile.
After high school, he studied at the New World School of the Arts in Miami, then entered Juilliard’s Drama Division in 1996, spending roughly four years in the program (Wikipedia biography). The result was a Bachelor of Fine Arts in acting — a credential that separates Howerton from the improv-and-luck origin story of many sitcom stars.
What is Glenn Howerton’s net worth?
- CelebrityNetWorth, the celebrity finance tracker, estimates Howerton’s net worth at $25 million — a figure built largely from his Always Sunny work plus his writing and producing credits.
It’s an estimate, not a bank statement. The number circulates widely, but no official financial disclosure backs it up.
Is Charlie married to the waitress in real life?
- Yes. Charlie Day, who plays Charlie Kelly, is married in real life to Mary Elizabeth Ellis, the actress who plays the Waitress.
The running gag of Charlie’s obsession gets a much happier real-world ending.
Howerton’s comedy looks unstudied on screen, but it sits on top of four years of classical training at Juilliard — which helps explain why Dennis Reynolds can flip from absurd to menacing in a single line.
The pattern: Howerton’s résumé keeps repeating itself — formal training underneath outrageously informal characters. That combination is the real story of his career so far.
Did Glenn Howerton try to leave It’s Always Sunny?
This is the rumor that refuses to die. Fan forums have repeated for years that Howerton tried to leave the show, wanted to move on to bigger projects, or was on the verge of being written out. None of it shows up in the actual production record: he has remained a core cast member, and his credit list runs continuously through the series (IMDb credit list).
Do Dennis and Dee sleep together?
- No. The suggestion is a long-running joke — the Gang and the audience both seem to wonder — but the show has never depicted Dennis and Dee as a couple.
The joke works because the characters act like a bickering married couple while insisting nothing is going on.
Who gets Dee pregnant?
- The storyline deliberately keeps the father ambiguous. Dee’s pregnancy arc involves multiple possible fathers, and the show uses the mystery for comedy rather than a clean reveal.
Fans still argue about the answer, which is part of why the question remains a fixture in fan forums.
Why was the episode “Dee Day” banned?
- The episode “Dee Day” was pulled from circulation because its content was judged offensive in hindsight.
It’s a reminder that Always Sunny built its reputation on purposefully uncomfortable comedy — and some jokes didn’t age well enough to keep airing.
Every “Howerton is leaving” headline starts from the same place: Dennis Reynolds is so convincingly awful that fans assume the actor must be desperate to escape him. The credit record says otherwise.
Why this matters: the show’s longevity depends on its core cast staying locked in, and the founding trio has held the creative core together for over two decades.
Who created It’s Always Sunny?
It’s Always Sunny in Philadelphia was created by Rob McElhenney, Glenn Howerton, and Charlie Day, and it premiered in 2005 (Wikipedia biography). It’s the rare sitcom where the people in front of the camera also control what happens behind it — Howerton is a writer and executive producer as well as a star, which means Dennis Reynolds isn’t just a performance. It’s a character he has shaped in the writers’ room for more than two decades.
Is Charlie autistic in It’s Always Sunny?
- The show never gives Charlie Kelly an official diagnosis. Fans have long pointed to traits they read as autistic, but the series itself treats Charlie’s behavior as a comic pattern, not a medical condition.
It’s a topic fans continue to debate, and the show’s writers have never settled it on screen.
Glenn Howerton in ER and Fargo
- ER: Howerton took dramatic guest roles early in his career, including appearances on the long-running medical drama.
- Fargo: He later appeared in FX’s anthology crime series Fargo — a casting choice that let him play outside the comedy lane.
The throughline, per his Vanity Fair interview: Howerton has spent the years since Dennis’s rise deliberately proving he can do more than one thing.
The trade-off: the same role that made him famous also made him easy to type-cast. The dramatic detours are his argument against it.
What is Glenn Howerton’s illness?
There is no verified record of Glenn Howerton having a serious illness. The rumor appears to be a case of the character swallowing the actor: Dennis Reynolds is written as a narcissist whose certainty about his own superiority sits at the center of the show’s dark-comedy framework, and clips of that performance read differently to viewers who don’t know the show.
To be direct: Dennis’s personality is a performance. No verified source has ever documented a matching health condition for Howerton.
What is Glenn Howerton’s height?
- There’s no authoritative public measurement. Fan databases list different figures, and Howerton hasn’t made his height a confirmed biographical data point.
If a website gives you a precise number, treat it as a database guess, not a fact.
Glenn Howerton young
- His early life: born in Japan in 1976, childhood years in England and South Korea, then a home in Montgomery, Alabama, before heading to Juilliard via Miami’s New World School of the Arts.
That’s the documented arc — and, in a career full of absurd characters, it’s the least absurd part of his story.
The takeaway: when a celebrity “illness” rumor has no source, no diagnosis, and no named outlet behind it, the most likely explanation is that search results are echoing a sitcom character’s personality.
What’s confirmed and what’s still unclear
The reliable list is short; the rumor list is longer, which is what happens when a character this convincing starts to blur with the actor.
Confirmed facts
- Glenn Howerton played Dennis Reynolds across the series’ run (IMDb show page).
- He co-created the show with Rob McElhenney and Charlie Day (Apple TV show profile).
- He graduated from Juilliard’s Drama Division with a BFA (Bachelor of Fine Arts).
What’s unclear
- Whether Howerton ever seriously considered leaving Always Sunny (fan rumor only).
- What the “illness” rumors are based on (no verified source).
- His exact net worth (CelebrityNetWorth’s $25 million is an estimate).
- His height (no primary-source measurement).
Read that list again: the confirmed side is shorter, but every item on it is backed by a named source. The unclear side is longer because fan culture rewards volume over verification.
In their own words
Two voices matter most in any conversation about Howerton’s career: his own, and the co-creator who built the show with him.
“Dennis is a sociopath,” Howerton has said more than once of the character he plays in It’s Always Sunny in Philadelphia.
— Glenn Howerton, Vanity Fair interview
“The show is about people who are always wrong but never doubt themselves,” Rob McElhenney, the series’ co-creator, has said of the world Howerton helped build.
— Rob McElhenney, co-creator of It’s Always Sunny in Philadelphia
Neither quote pretends that Dennis Reynolds is a nice guy. The difference is that Howerton and McElhenney know it’s fiction — which is more than the rumor mill can say.
The takeaway
Glenn Howerton’s career is the rare case where the most famous thing an actor has done is also the thing that obscures everything else. Dennis Reynolds made him a star; Juilliard, ER, Fargo, and BlackBerry prove the range behind it. For the viewer whose only frame of reference is Dennis Reynolds, the decision is easy: watch him in BlackBerry or Fargo, and the distance between character and actor becomes obvious.
