Rob McElhenney’s Initial Hesitation to Cast Kaitlin Olson in It’s Always Sunny in Philadelphia
It’s Always Sunny in Philadelphia has become one of the longest-running live-action sitcoms in TV history, thanks to its chaotic humor and unforgettable characters. Among them, Kaitlin Olson’s portrayal of the delusional and often-deranged Dee Reynolds is iconic. However, co-creator and star Rob McElhenney initially had reservations about casting Olson in the role.
Why McElhenney Was Reluctant to Cast Olson
In early interviews and behind-the-scenes discussions, McElhenney admitted that he hesitated to cast Olson—not because of her talent, but because of their real-life relationship. At the time, the two were dating, and McElhenney worried that mixing personal and professional dynamics could complicate things.
“I was concerned about what it would mean for our relationship,” McElhenney revealed in a 2018 interview with The Hollywood Reporter. “If things didn’t work out on the show, it could have been disastrous for us personally.”
Despite his hesitation, Olson auditioned and immediately won over the team with her comedic brilliance. Co-creator Glenn Howerton and Charlie Day pushed for her, recognizing her perfect fit for Dee’s abrasive yet hilarious personality.
How Olson Proved Herself as Dee Reynolds
Olson’s performance as Dee—often referred to as the “gang’s bird” and subjected to relentless insults—became a standout element of the show. Her physical comedy, sharp timing, and willingness to embrace absurdity (like her failed attempts at fame or her alter ego, “Sweet Dee”) made her indispensable.
Fans and critics alike praised Olson’s ability to hold her own against the male-dominated cast. In a Rolling Stone retrospective, TV critic Alan Sepinwall noted:
“Kaitlin Olson is the show’s secret weapon. While the guys spiral into madness, Dee’s delusional self-importance makes her the perfect foil.”
Even McElhenney later admitted that his initial doubts were unfounded. The couple married in 2008 and have since worked together seamlessly, proving that their professional collaboration only strengthened their relationship.
Fan Reactions and Social Media Love
Olson’s portrayal of Dee has inspired countless memes and fan tributes. A popular YouTube supercut, “Sweet Dee’s Best Moments”, showcases her most unhinged scenes, amassing millions of views.
Twitter users frequently celebrate her underrated genius:
“Kaitlin Olson as Dee is one of the greatest comedic performances ever. The way she commits to the bit is unmatched.” – @SunnyFanatic
“The fact that Rob almost didn’t cast Kaitlin is wild. Imagine Always Sunny without Sweet Dee? Unthinkable.” – @PhillyComedyNerd
The Legacy of Dee Reynolds
Sixteen seasons in, Dee remains a cornerstone of It’s Always Sunny. Olson’s fearless approach to comedy has influenced female characters in raunchy comedies, breaking the stereotype that women can’t be as outrageous as men in humor.
McElhenney’s initial hesitation is now a fun footnote in the show’s history—one that highlights how the best casting choices sometimes come from taking risks.
Conclusion
What started as a personal concern turned into one of the show’s greatest strengths. Kaitlin Olson’s Dee Reynolds is now irreplaceable, proving that sometimes, the best decisions are the ones we initially resist.
Would Always Sunny be the same without her? Not a chance.
