Code Name: Diamond Head

Name: Code Name: Diamond Head
Genre: Crime, Drama, TV Movie
Released: 1977
Cast: Roy Thinnes, France Nuyen, Zulu, Ward Costello, Don Knight

A 1977 TV movie pilot about a Hawaii-based counter-intelligence agency fighting international crime. It's earnest '70s spy fiction with a pulpy edge—colorful characters, exotic locations, goofy codenames. For anyone who enjoys that particular brand of groovy-era espionage kitsch, or who's curious about forgotten television history and why certain shows never made it past the audition.

Should you watch it?

Watch it if you enjoy unpolished 1970s spy-caper pilots, the kind that never got a series, where the appeal is the retro island setting and a cast of faces you half-recognise.

Skip it if you want tight plotting and modern pacing, since this is a single 78-minute TV movie whose plot may feel thin stretched around its gimmicks.

What it asks of you: Settle in for a brisk seventy-eight minutes of old-fashioned episodic storytelling, with an easygoing rhythm, light sleuthing and no real darkness to sit through.

If you liked this

The Man from U.N.C.L.E.1964

Stylish spy series with charismatic leads, witty banter, and gadgetry galore. Set a template for '60s espionage television that Code Name: Diamond Head is clearly trying to recapture, though with distinctly '70s sensibilities.

But Episodic format means plots are often straightforward; some find the tone campy rather than thrilling.

Mission: Impossible1966

Ingenious heist-driven spy series where elaborate plans unfold with satisfying precision. Shares Diamond Head's love of international intrigue and ensemble teamwork against shadowy threats.

But Very talky. The early seasons especially spend a lot of time on exposition and plan-building rather than action.

Hawaii Five-O1968

Set in the same Hawaiian locale, this is slick crime-fighting television with style and punch. If you liked Diamond Head's setting and spy-agency structure, Five-O perfects that formula with better writing.

But Tone is more serious and less colorful than the spy-camp vibe Diamond Head attempts.

The wildcard

Something you would not have found on your own.

Live and Let Die1973

Both are 1970s spy entertainment that prioritizes visual flair and character color over narrative coherence, treating the world as a series of exotic backdrops for agency operatives.

Roger Moore's Bond debut is exactly contemporary with Diamond Head and shares its embrace of '70s exoticism, colorful villains with ridiculous names, and a casual approach to international locales as playground for espionage. Pure style over substance, unapologetic.

But The racial politics are uncomfortable by modern standards; it's also wildly uneven in tone, oscillating between camp and violence.

The Saint1962

Suave adventure-thriller with a charming lead playing a gentlemanly rogue. Captures that same globetrotting espionage energy with style, humor, and an undercurrent of genuine danger.

But Episodic storytelling can feel dated; some plots are thin vehicles for the lead's charisma rather than substantive narratives.

The Avengers1961

British spy-fi with surreal style, elegant characters, and a knowing sense of humor about spy-movie tropes. Proves the genre could be smarter and weirder than Diamond Head's earnest approach.

But Can be very theatrical and arch; if you want grounded spycraft, this abstracts away from realism entirely.

Department S1969

Action-packed British series about an international intelligence unit solving impossible crimes. Sleek production values and a globe-trotting scope that makes Diamond Head's ambitions look modest.

But Lesser known and harder to find; tonal inconsistency between episodes varies wildly.

Mannix1967

Stylish detective series with a likable protagonist and solid plotting. A different flavor of '70s intrigue—private eye instead of government agent—but the same commitment to action and character.

But Episodic crime-of-the-week format; earlier seasons are stronger than later ones.

Spy Game2001

Modern spy thriller that mirrors Diamond Head's structure of seasoned agents using teamwork and cunning. Brad Pitt and Robert Redford together, with slick action and genuine chemistry.

But Slicker than necessary; some find it superficial despite the quality cast.

The Spy Who Came In from the Cold1965

Serious adaptation of le Carré's novel that grounds spy fiction in moral ambiguity and human cost. Shows what the genre can do when it takes itself seriously rather than playing it for thrills.

But Bleak, slow, and deliberately unsexy—the opposite of Diamond Head's adventurous tone.

The Spy Who Came In from the Cold poster

Thunderball1965

Identical plot premise: intelligence operatives racing to stop theft of a WMD (nerve gas instead of nuclear warheads) being sold to hostile powers.

Lavish Bond film with the exact structure Diamond Head attempts—international agency, diverse team, exotic location, plot to steal and ransom a weapon of mass destruction. Shows what that template looks like with unlimited budget and Sean Connery.

But Bloated at nearly two and a half hours; the underwater sequences drag; dated gender politics throughout.

Colossus: The Forbin Project1970

Both are 1970s films about intelligence agencies and governments trying to control powerful forces and contain threats, but where Diamond Head is colorful pulp, Colossus is sober speculation about what happens when control fails.

Intelligent sci-fi thriller about an AI defense system that becomes sentient and holds the world hostage. A radically different beast from Diamond Head, but shares its '70s spy-thriller DNA and treats impossible scenarios with deadly seriousness.

But Slow-paced hard sci-fi with minimal action; dialogue-heavy and conceptually demanding; a dour film that makes no concessions to entertainment.
