The cast of It’s Always Sunny in Philadelphia came together this week to celebrate a major milestone — the 80th birthday of their beloved co-star, Danny DeVito. Rob McElhenney, Charlie Day, Kaitlin Olson, and Glenn Howerton paid heartfelt tribute to the legendary actor, whose larger-than-life presence has been at the heart of the show since 2006. Fans across the world joined in, sharing memories, quotes, and clips from DeVito’s most unforgettable moments as Frank Reynolds.
Rob McElhenney took to social media with a touching message, calling DeVito “a legend, a friend, and the beating heart of Sunny.” He shared behind-the-scenes photos of the cast laughing together between takes, reminding fans that beyond the outrageous comedy, the team has always been a tight-knit family. “We wouldn’t be here without him,” McElhenney wrote.
Danny DeVito joined It’s Always Sunny in Philadelphia in its second season, transforming the small FX sitcom into a cultural phenomenon. His portrayal of Frank Reynolds — a chaotic, scheming, and often unhinged father figure — became one of television’s most iconic roles. What began as a dark comedy with a cult following has grown into one of the longest-running live-action sitcoms in U.S. television history.
As DeVito reached his 80th birthday, fans reflected on how seamlessly he bridged generations. Known to older audiences for classics like Taxi, Matilda, and Batman Returns, he found a second wave of fame with Sunny, endearing himself to a whole new era of comedy lovers. His ability to embrace absurdity with sincerity made Frank Reynolds both ridiculous and strangely lovable.
Kaitlin Olson shared a heartfelt post, describing DeVito as “the most generous scene partner and an absolute joy to work with.” She added, “Every day with Danny is a masterclass in timing, fearlessness, and kindness.” Her words echoed what many in the industry have long said — that DeVito’s energy on set is infectious and his professionalism unmatched.
Charlie Day reflected on how DeVito’s arrival changed everything for the show. “When Danny came aboard, we were just a bunch of kids making something weird,” he said in an interview. “He gave us legitimacy, but he also gave us courage to push boundaries even further.” Fans have often credited DeVito with helping the show refine its tone — balancing outrageous humor with a touch of heart.
Glenn Howerton, who plays Dennis Reynolds, joined in the celebration by posting a throwback video montage of DeVito’s funniest scenes. “Eighty years young and still outshining us all,” he joked. The video quickly went viral, amassing hundreds of thousands of views and reminding fans why Frank’s unpredictable antics — from couch-surfing to wrestling as “The Trash Man” — have become internet gold.
Beyond the show, Danny DeVito’s influence stretches far beyond Hollywood comedy. Over a career spanning six decades, he has worked as an actor, director, and producer, leaving an indelible mark on film and television. His commitment to the craft, along with his sharp wit and humanity, have earned him the admiration of both peers and audiences around the world.
In interviews, McElhenney has often described how working with DeVito shaped his own creative path. “He’s fearless,” McElhenney said. “He’s not afraid to look silly, to commit fully, or to try something new — and that’s what makes him a genius.” The cast’s admiration is not just professional; it’s deeply personal. They often refer to him as their mentor and comedic compass.
As word of DeVito’s milestone birthday spread, tributes poured in from co-stars, directors, and fans alike. Countless posts celebrated not only his career achievements but his warmth and humor off-screen. Even those who had never met him felt compelled to share stories about how his performances brought them laughter during tough times.
Danny DeVito responded to the outpouring of love with typical humility and charm. In a short message to fans, he wrote, “Thanks for all the love, ya jabronis! Here’s to 80 more years of chaos.” The post quickly racked up thousands of comments and reactions, with fans joking that Frank Reynolds would probably live forever — fueled by rum ham and pure mischief.
As It’s Always Sunny in Philadelphia continues its record-breaking run, DeVito’s presence remains as vital as ever. At 80, he stands as a testament to creative longevity, joy, and the enduring power of comedy. For fans and colleagues alike, celebrating Danny DeVito isn’t just about marking another year — it’s about honoring a living legend who continues to make the world laugh, one outrageous moment at a time.
