The phrase “Book ’em, Danno” is perhaps one of the most recognizable catchphrases in the history of global television. It serves as the quintessential sign-off for a series that has defined the cultural image of Hawaii for over half a century. But behind the catchphrase are the actors who brought the character of Detective Danny Williams to life, transforming him from a secondary partner into a central pillar of the “Five-0” legacy. For those visiting Honolulu or the wider island of Oahu, the shadow of Danno and the elite task force is everywhere, from the historic buildings of the city center to the rugged cliffs of the coastline.
The Evolution of Danny “Danno” Williams in Television History
The character of Danny Williams has been portrayed by two distinct actors across two different eras of television, each bringing a unique energy to the role and reflecting the changing landscape of the United-States and its relationship with the islands.
James MacArthur: The Original Danno
In the original series, which aired from 1968 to 1980, Danny “Danno” Williams was played by James MacArthur. MacArthur brought a professional, stoic, and reliable presence to the screen. As the right-hand man to Steve McGarrett (played by Jack Lord), MacArthur’s portrayal was instrumental in establishing the show’s procedural authority. During this era, Hawaii was still a relatively new state, having joined the union only nine years before the show premiered. MacArthur’s Danno represented the bridge between the mainland’s expectations of law and order and the exotic, often misunderstood environment of the Pacific-Ocean islands.
MacArthur appeared in 11 of the 12 original seasons. His departure before the final season marked a significant shift in the show’s dynamic, proving just how vital the “Danno” character was to the “Five-0” formula. For fans of classic television visiting Honolulu, MacArthur’s legacy is often felt when touring the historic Aliiolani-Hale, the building used as the exterior for the task force’s headquarters.
Scott Caan: The Modern Interpretation
When the series was rebooted in 2010, the role was reimagined for a modern audience. Scott Caan took over the mantle of Danny Williams, but with a twist. Unlike the original Danno, who was a local fixture, Caan’s version was a “haole” (newcomer) from New Jersey. This Danno was a fish out of water, providing a comedic yet heartfelt perspective on the local culture. His constant “cargument” banter with Alex O’Loughlin’s Steve McGarrett became the heartbeat of the reboot.
Caan’s portrayal earned him a Golden Globe nomination and helped propel the reboot to a decade of success. His character’s struggle to adapt to the island lifestyle—often complaining about the heat, the traffic, and the lack of a good pizza—actually endeared the show to residents of Oahu and tourists alike. It highlighted the real-world experience of many visitors who find themselves initially overwhelmed by the “Aloha Spirit” before eventually falling in love with it.
Cultural Impact: How Hawaii Five-0 Shaped Global Perceptions
The “Five-0” franchise did more than just provide entertainment; it acted as a massive tourism engine for the islands. Before the show, many people in the United-States and abroad viewed Hawaii as a distant, unreachable paradise. The series brought the sights, sounds, and culture of the islands into living rooms weekly.
Showcasing the Spirit of Aloha
While the show focused on crime-fighting, it deeply integrated the concept of “Ohana” (family) into its storylines. Whether it was the original team or the modern squad, the bond between the characters mirrored the community-centric culture of Hawaii. This emphasis on local values encouraged a more respectful form of tourism. Visitors weren’t just coming for the beaches at Waikiki; they were coming to experience a culture that valued history, land, and community.
Modern Tourism and the “Five-0” Effect
The reboot in 2010 saw a surge in “Five-0” related tourism. Local businesses and filming locations became pilgrimage sites for fans. The show often featured local food, such as the famous malasadas from Leonards-Bakery or plate lunches from Rainbow-Drive-In. This exposure provided a significant boost to the local economy, proving that a character like Danno could serve as an ambassador for the islands’ culinary and social life.
Exploring the Iconic Filming Locations Across Oahu
For any traveler who has spent hours watching McGarrett and Danno chase suspects through the streets of Honolulu, visiting the actual filming locations is a top-tier activity. The island of Oahu serves as a living set, and many of the most famous backdrops are easily accessible to the public.
Aliiolani Hale and the King Kamehameha I Statue
Perhaps the most iconic location is Aliiolani-Hale, which serves as the home of the Hawaii State Supreme Court. Fans recognize it immediately as the headquarters of the Five-0 task force. Standing proudly in front of the building is the King-Kamehameha-I-Statue, a major landmark that honors the monarch who unified the islands. This area is a must-visit for anyone interested in both the show and the actual history of Hawaii.
Iolani Palace: A Royal Connection
Located just across the street from Aliiolani-Hale is Iolani-Palace. In the original series, this historic site—the only royal palace on soil in the United-States—was used for exterior shots of the team’s office. Today, it stands as a solemn reminder of the Hawaiian Kingdom’s history and is one of the most significant landmarks in the world. Visitors are encouraged to take a guided tour to understand the deep cultural roots that the show often referenced.
The Natural Wonders: Diamond Head and Kualoa Ranch
The action sequences of Hawaii Five-0 often took place against the backdrop of Hawaii’s stunning natural beauty. Diamond-Head, the volcanic tuff cone that looms over Waikiki-Beach, frequently appeared in aerial shots. Hiking to the summit of Diamond-Head offers fans a “Five-0” eye view of the coastline.
For the more rugged jungle scenes, the production frequently utilized Kualoa-Ranch on the windward coast of Oahu. Known as “Hawaii’s Backlot,” this private nature reserve has been the setting for numerous films and TV shows. Travelers can take movie site tours to see where McGarrett and Danno navigated through the dense tropical greenery.
A Fan’s Guide to Experiencing Hawaii Five-0 Culture Today
Beyond just visiting buildings, fans can immerse themselves in the lifestyle depicted in the show. This involves engaging with the local food scene and exploring the lesser-known corners of the island.
Local Grinds and Screen-Famous Eateries
Food is a central character in the Hawaii Five-0 reboot. Kamekona’s Shrimp Truck may be a fictional business, but the culture of North Shore shrimp trucks is very real. Travelers heading to the North-Shore can find plenty of authentic trucks that offer the same garlic shrimp that Danno and the team frequently enjoyed.
For a true “Five-0” morning, a stop at Leonards-Bakery is essential. Their hot, sugar-coated malasadas are a local staple. Similarly, the Rainbow-Drive-In in Honolulu offers the classic plate lunch—two scoops of rice, macaroni salad, and an entree like mahi-mahi or shoyu chicken—that fuels the characters between cases.
Coastal Drives and Scenic Lookouts
To truly feel like you’re in a “Five-0” chase sequence (minus the speed), a drive along the H-1 and the Kalanianaole-Highway is highly recommended. The views of the Pacific-Ocean are breathtaking. Along the way, stop at the Halona-Blowhole or Hanauma-Bay, both of which have been featured in countless episodes.
For those looking for a more reflective experience, the National-Memorial-Cemetery-of-the-Pacific, located in the Punchbowl-Crater, is a significant site. The show often portrayed McGarrett visiting his father’s grave here, and in real life, it is one of the most peaceful and respectful landmarks in Honolulu.
Legacy and Longevity: Why Danno Remains a Beloved Character
The question of “Who played Danno?” usually leads to a deeper conversation about why the character matters. Danno is the human element of the high-stakes world of Five-0. Whether it was James MacArthur’s steady professionalism or Scott Caan’s fierce loyalty and witty banter, Danno represents the “partner” we all wish we had.
In the context of Hawaii tourism, Danno serves as the proxy for the visitor. Through his eyes, we see the beauty of the Byodo-In-Temple in the Valley of the Temples, the bustling energy of the Ala-Moana-Center, and the quiet majesty of a sunset at Magic-Island. He reminds us that while the scenery is stunning, it is the people and the relationships—the “Ohana”—that make the islands truly special.
For those planning a trip to Oahu, following the trail of Hawaii Five-0 is more than just a fan activity; it is a comprehensive guide to the best the island has to offer. From the luxury resorts like the Hilton-Hawaiian-Village—which was a frequent filming site—to the historic shores of Pearl-Harbor, the spirit of Danno and the Five-0 team continues to invite travelers to explore the rich tapestry of the 50th state. Whether you are a fan of the 1968 classic or the 2010 hit, the invitation remains the same: come to the islands, experience the culture, and as always, book ’em.
