Glenn Howerton: Why Did He Leave, Illness, and Net Worth

It’s a peculiar thing about fame: the more recognizable an actor becomes for one role, the more the questions about their personal life tend to snowball. Glenn Howerton, the man behind It’s Always Sunny in Philadelphia‘s Dennis Reynolds, attracts a whirlwind of search queries — did he leave the show, is he sick, how much does he make? — but the answers are often simpler than the speculation.

Who is the famous actor named Glen?

Why the spelling matters

  • The correct spelling of his given name is “Glenn” with a double ‘n’.
  • Misspellings often omit the second ‘n’, which leads to confusion in searches and databases.

Glenn Howerton’s breakout role

  • TVmaze (television database) credits him as Dennis Reynolds across 183 episodes of It’s Always Sunny in Philadelphia.
  • He co-developed the series and has served as a writer and executive producer throughout its run, according to Wikipedia (crowd-sourced encyclopedia).

Early life and family

  • Born on April 13, 1976 in Japan, where his father was stationed as a decorated U.S. Navy fighter pilot (Wikipedia (crowd-sourced encyclopedia)).
  • He grew up in various parts of the world before pursuing acting and theatre in the United States.

The implication is clear: the biographical record is stable and well documented, yet the confusion arises from simple name misspellings and character bleed.

How did the Always Sunny cast meet?

Who created Always Sunny?

  • Rob McElhenney created It’s Always Sunny in Philadelphia and stars in it alongside Glenn Howerton and Charlie Day.
  • The show began as a low-budget independent pilot written by the trio before being picked up by FX.

Why is Always Sunny not cancelled?

  • The show has been renewed repeatedly across two decades, airing its 16th season in 2023 (TVmaze (television database)).
  • Strong syndication deals and a devoted cult following have made it one of the longest-running live-action sitcoms in history.

The cast additions over the years

  • Danny DeVito joined the cast in season 2, playing Frank Reynolds.
  • Kaitlin Olson has played Dee Reynolds since the show went to air.
Why this matters

The core cast’s stability across 16 seasons provides a strong baseline against which to judge rumours of departure. Every persistent cast member weakens the premise of a permanent exit.

The pattern here is remarkable longevity: the core five actors have remained together for nearly two decades, making departure rumours the exception rather than the rule.

Why did Glenn Howerton leave season 13?

Was Glenn Howerton going to leave Always Sunny?

  • Howerton reportedly considered leaving It’s Always Sunny after season 12 to pursue other opportunities (Australian News Desk (fact-checking outlet)).
  • Reporting characterizes the possible departure as career-driven rather than health-related.

What was A.P. Bio?

  • A.P. Bio was a NBC comedy sitcom where Howerton played the lead character, principal Jack Griffin.
  • Its production schedule in 2018 caused significant scheduling conflicts with Always Sunny season 13 (Australian News Desk (fact-checking outlet)).

How did Howerton return?

  • A.P. Bio was cancelled after four seasons, wrapping in 2021.
  • Howerton returned to a fuller participation in Always Sunny seasons 14 through 16.
  • His credit placement in early season 13 caused confusion: the It’s Always Sunny Wiki (fan wiki) documents that he was omitted from the opening title sequence of the first episode but received a starring credit in the closing credits, returning to normal placement by episode 2.
Bottom line: Glenn Howerton did not permanently leave It’s Always Sunny in Philadelphia. His season 13 role was reduced specifically because he was committed to his own NBC sitcom A.P. Bio, and he returned to a full schedule after it ended.
The trade-off

Chasing a network lead role in A.P. Bio meant a lighter schedule on Paddy’s Pub for one season. Howerton gambled on a solo vehicle while keeping his seat at the Sunny table — a compromise, not an ejection.

The catch: a reduced commitment for one season was never a final exit. Career scheduling, not creative discord or health, drove the shift.

What is Glenn Howerton’s illness?

Where did the illness rumor come from?

  • No reliable documented origin for a serious illness rumor exists in the available reporting (Australian News Desk (fact-checking outlet)).
  • One theory points to a visible facial bump in promotional photos, described as a benign cyst without primary medical documentation.

How Dennis Reynolds differs from Howerton

  • Dennis Reynolds is a narcissistic, manipulative character whose on-screen volatility bleeds into audience perception.
  • The illness rumor likely stems from confusion between the character’s psychological traits and the actor’s real life.

Has Howerton addressed the rumor?

  • No direct public statement from Howerton addressing a specific illness rumor can be verified in the available reporting.
  • The only documented health detail is a mention in Wikipedia (crowd-sourced encyclopedia) of an ADHD diagnosis in 2023.
Bottom line: Glenn Howerton has no publicly documented serious illness. The rumour appears to be entirely a result of confusion between the actor and the volatile character he plays.
The upshot

Without a credible source or a statement from the actor, the illness rumor stands as an unsubstantiated piece of internet noise.

What this means: the absence of a credible health story is the story. When a known actor remains consistently productive, wellness rumours dissolve for lack of evidence.

How much does Glenn Howerton make per episode?

How rich is Glenn Howerton?

  • Celebrity Net Worth, cited by BritainBulletin (celebrity news aggregator), estimates Howerton’s net worth at $25 million.
  • Other estimates vary widely: True North Brief (biographical profile) reports roughly $8 million, while News Shift (lifestyle outlet) places it at $12 million.
  • The available estimates are not official financial statements and may differ substantially from actual figures.

What actors make $1 million per episode?

  • $1 million-per-episode deals are rare and generally tied to top A-list television stars.
  • Typical Always Sunny cast contracts are not publicly known to fall into that tier.

Why the salary figure is not public

  • TV and streaming contracts are rarely disclosed outside of industry reporting.
  • No union rate sheet or leaked contract for Howerton’s episode pay exists in the public record.
Bottom line: Howerton’s per-episode salary is entirely unknown to the public. Net worth estimates range from $8 million to $25 million, but none of these figures are officially verified.

The implication: without a union rate sheet or leaked contract, published net worths are best treated as informed speculation, not fact.

Why did they replace Dee on Always Sunny?

Does Dee wear a wig in Always Sunny?

  • Wig and hair style questions are recurring production trivia that do not imply any main-cast change.
  • Kaitlin Olson has played Dee Reynolds consistently since the series aired.

Was Dee actually pregnant during It’s Always Sunny?

  • Whether Olson was pregnant during specific seasons is not documented in the available career profiles, though such storylines are common in long-running sitcoms.

How Kaitlin Olson became Dee

  • The original unaired pilot cast a different actress as Dee.
  • Olson replaced her before the show went to air, solidifying the core cast.
The paradox

For a show that famously kept its cast intact, the early Dee swap is the exception that proves the rule — and generates more trivia than the rest of the cast’s stability ever did.

The trade-off: replacing an actress in an unaired pilot is standard television, but for a show with a famously stable cast, every early detail becomes trivia.

Perspectives on the story

“Glenn Howerton co-developed It’s Always Sunny in Philadelphia and has served as a writer and executive producer on the series.”
— Wikipedia (crowd-sourced encyclopedia)

“No reliable medical source confirms that Howerton has publicly disclosed a serious illness.”
— Australian News Desk (fact-checking outlet)

“The show has been renewed repeatedly; it aired its 16th season in 2023.”

For the searcher wondering whether Glen or Glenn Howerton is unwell, departed, or underpaid, the answer across each axis is the same: the documented career record shows no evidence of any of these claims. The real story is how a stable two-decade career generates enough ambiguity in search results to make absence and illness seem plausible. The distinction between actor and character, between a reduced season and a permanent exit, is the gap that rumor fills — and the record easily closes.
