Get ready for another uproarious, chaotic holiday as the Griswold family returns in National Lampoon’s Christmas Vacation 3: Holiday Heritage (2026). Starring Chevy Chase, Beverly D’Angelo, Juliette Lewis, and Johnny Galecki, this hilarious third installment takes the beloved family on their wildest Christmas adventure yet—one filled with technology gone haywire, old traditions colliding with modern conveniences, and the kind of holiday chaos that only the Griswolds can deliver.
Clark Griswold (played by Chevy Chase) is back, older but no less determined to create the perfect Christmas—this time, as a grandfather. Now living in a retirement condo in sunny Florida, Clark is still driven by his passion for Christmas and the “Griswold Family Christmas” traditions. But his new generation of grandkids is far more interested in their screens than in any holiday cheer, so Clark takes it upon himself to pass down the Christmas spirit in the most Griswold way imaginable—by going completely overboard with a “Smart Home” light display controlled by AI.
Naturally, things don’t go as planned. What begins as a light-hearted attempt at holiday magic quickly spirals into an out-of-control disaster. The AI-powered lights revolt, plunging the entire state of Florida into darkness. Clark’s optimistic mania is as high as ever, but this time, he’s facing off against a rogue tech system—and a very patient Ellen Griswold (played by Beverly D’Angelo), who is just trying to keep the family from imploding. Ellen is the ever-patient anchor in the storm of Griswold chaos, trying to hold everything together while the tech and family drama go off the rails.
Joining the madness are Rusty Griswold (played by Johnny Galecki) and Audrey Griswold (played by Juliette Lewis), who return with their own chaotic families in tow. From a drier-than-ever turkey to a Christmas tree that could double as a forest, nothing is as it seems when the Griswolds are involved. Even the infamous squirrel from the first film is replaced with a rogue delivery drone that causes its own mayhem.
But just when you think it can’t get any worse, an unexpected blizzard hits their tropical paradise. Now, the Griswolds must huddle together for warmth, sanity, and survival, proving that family is the only thing that can keep them going. With old-school traditions clashing with modern technology, it’s a hilarious collision of analog chaos and digital disasters.
National Lampoon’s Christmas Vacation 3: Holiday Heritage is a riotous celebration of family, tradition, and, of course, disaster. The holiday spirit is alive and well, even if it’s wrapped in tangled lights and faulty tech. It’s a nostalgic return to the Griswold chaos that fans know and love, with Chevy Chase bringing his signature manic optimism and slapstick humor to the forefront.
While the fuses may blow, the sewer may back up, and the lights may flicker out, there’s one thing the Griswolds know for sure: nothing can extinguish the burning love of family—even if it sometimes involves a little bit of fire and a lot of chaos.
Movie Rating: 8.9/10 – A hilarious clash of old-school traditions and modern-day disasters, Christmas Vacation 3 is the perfect blend of nostalgia and new laughs for the whole family.
