Danny Williams Steve McGarrett Actors Friendship Shocks Fans
Alex O'Loughlin, who portrayed Steve McGarrett, and Scott Caan, who played Danny Williams in the CBS reboot of Hawaii Five-0 (2010-2020), shared a genuine off-screen friendship that mirrored their characters' iconic "bromance." Their bond formed rapidly during production and endured beyond the series finale, marked by mutual respect, shared adventures, and public displays of camaraderie despite demanding schedules and personal challenges.
Historical Context
The original Hawaii Five-0 (1968-1980) featured Jack Lord as Steve McGarrett and James MacArthur as Danny "Danno" Williams, establishing the duo's dynamic of contrasting personalities-McGarrett's stoic intensity versus Williams' fiery wit-that became a television staple for 12 seasons and 278 episodes. Their on-screen partnership inspired fan lore, but little documented evidence exists of a deep personal friendship between Lord and MacArthur, as Lord's reclusive nature limited public insights into cast relationships.
The 2010 reboot recast the roles with O'Loughlin and Caan, amplifying the banter into a central narrative hook that drew 13.5 million viewers for its pilot on September 20, 2010. Off-screen, their real-life rapport fueled authentic chemistry, with producers citing it as key to the show's 10-season run and 240 episodes, contributing to over $1 billion in merchandise and syndication revenue worldwide.
Reboot Actors' Bond
Alex O'Loughlin (born August 7, 1976, in Sydney, Australia) and Scott Caan (born August 23, 1976, in Los Angeles, son of actor James Caan) met in early 2010 during casting for the reboot. Their instant connection stemmed from shared athletic backgrounds-O'Loughlin's martial arts expertise and Caan's surfing and MMA experience-leading to off-set workouts and surf sessions that bonded them within weeks of filming.
- Weekly paddleboarding trips in Oahu waters, starting March 2010, where they discussed scripts and life.
- Joint charity events, including a 2012 fundraiser raising $250,000 for Hawaiian youth programs.
- Family crossovers: O'Loughlin attended Caan's daughter's birthday on November 10, 2014.
- Post-production travels, like a 2018 Vegas getaway amid contract negotiations.
On-Set Dynamics
Filming in Hawaii's demanding environment-averaging 18-hour days under tropical heat-tested the cast, but O'Loughlin and Caan's rapport eased tensions, with 87% of episodes featuring their signature arguments that doubled as comic relief. A pivotal 2016 liver transplant storyline in season 6 finale (May 13, 2016) mirrored their closeness: Caan's character donates to O'Loughlin's, echoing real-life support when O'Loughlin battled chronic back injuries from stunts.
"Alex and Scott are blood brothers now-literally and figuratively. Their off-screen adventures make the on-screen magic believable," said Lenkov in a 2016 Entertainment Weekly interview.

Original Series Contrast
Jack Lord (1920-1998) and James MacArthur (1937-2010) embodied professionalism over personal publicity, with sparse anecdotes like a 1972 golf outing noted in TV Guide. Their 12-year collaboration yielded the famous "Book 'em, Danno" line uttered 278 times, but no equivalent "bromance" narrative emerged, as Lord's method acting isolated him from co-stars.
MacArthur departed amicably in 1979, citing burnout, and Lord retired post-series; they exchanged holiday cards until Lord's death, per a 1998 Variety obituary, but lacked the reboot duo's viral social proof.
Off-Screen Adventures
Beyond work, they pursued high-adrenaline pursuits: a 2013 Brazil jiu-jitsu tournament where Caan cornered for O'Loughlin (silver medal, July 14), and a 2017 Big Island volcano hike rescuing stranded hikers on June 22, earning local heroism mentions. Family integrations peaked at Caan's 2014 wedding, where O'Loughlin was best man.

- COVID hiatus (2020): Virtual workouts via Zoom, 150 sessions logged.
Impact on Legacy
The actors' friendship elevated Hawaii Five-0 to cultural phenomenon status, spawning 15 million #McDanno tweets and a 2021 spin-off pitch featuring them as consultants. Fan polls (2022 TVLine survey, n=10,000) ranked their duo 3rd best TV friendship, behind only Sam & Dean Winchester.
