The greatest movie ever made..!

Stylish but barely mediocre overall

The plot isn't so bad, but the pace of storytelling is too slow which makes people bored. Certain moments are so obvious and unnecessary for the main plot. I would've fast-forwarded those moments if it was an online streaming. The ending looks like implying a sequel, not sure if this movie will get one

It is an exhilarating, distressing, funny and profound film, with one of the more memorable film scores in years,

It doesn't take long to see why Code Name: Diamond Head didn't make it onto the network schedules. The TV pilot movie doesn't get past the credits before it's obvious just how bad it's going to be. Maybe I missed something, because the plot didn't make a whole lot of sense. Based on what I got out of the muddled mess, a terrorist or thief or something named "Tree" (Ian McShane) goes to Hawaii to steal something to do with a secret weapon. The world's dullest secret agent, Johnny Paul (Roy Thinnes), is out to stop him. There might have been more, but trust me – it really doesn't matter anyway.Action movies should have action. Suspenseful moments should have suspense. And dramatic moments should have drama. There's none of that in Code Name: Diamond Head. I've seen others use the word "turgid" to describe this made for TV snoozer – and it's better than any one word description I can come up with. None of the characters is in the least bit exciting or worth caring about. And Roy Thinnes makes for the worst leads imaginable. His charisma is just slightly north of a slug. Ian McShane is easily the best thing the movie has going for it, but unfortunately for everyone else involved, it doesn't appear he was going to be back as a regular cast member. Now if McShane had been cast in the series lead, well then you might have had something.I'm quickly discovering that these Gawd awful 70s made-for-TV movies make great Mystery Science Theater 3000 episodes. And that goes double if Quinn Martin was involved. Very funny stuff from Mike and the Bots. So while I may only give the movie a 3/10, I rate Episode #608 a 4/5 on my MST3K rating scale.

Ahh, the dull t.v. shows and pilots that were slammed together in the 70's to make equally dull t.v. movies! Some examples would be Riding With Death(the most hysterically cheesy of the lot), Stranded in Space(confusing and uninteresting), San Francisco International(horribly dull and unbelievably confusing), and this turgid bit of Quinn Martin glamor. Shot in Hawaii(although you wouldn't know it from the outside shots), it's apparently a failed pilot for a lame spy show. The real problem is that you don;'t like most of the characters, including the drab main character Diamond Head, who seemed half asleep for the entire movie; his boss 'Aunt Mary', who had a really weird delivery of his lines and shellacked white hair as well as the a tan that looked like it had been stuccoed on; Diamnd Head's girlfriend/fellow agent(hell, I can't even remember her name) a skinny, wooden woman with a flat way of speaking that is just not sexy or interesting; and the singing sidekick Zulu(again, i can't remember his character's name)who wasn't bad in small doses. The most interesting person in the whole production was Ian McShane, who sucked as a bad guy but still proved his acting chops. Alothugh the make-up jobs this so-called 'chameleon' used to disguise himself were just laughable. I have absolutely no idea what he was doing or what he was trying to steal from the lab that caused him to dress as a South American Dictator cum American General. Nor do I care. The plot simply wasn't interesting enough to hold your attention for even ten minutes at a time, let alone the hour and a half or so it goes on. Just call this one - Hawaii Five No!

Another turgid action/adventure flick from the Quinn Martin Productions factory. Roy Thinnes plays undercover agent Diamond Head (Mr. Head, to you), working for his G-Man handler "Aunt Mary", looking for "Tree", who's on a mission to...well, just watch the movie. This one deserved and got the full MST3K sendup. As the boys and various reviewers have pointed out, the movie "Fargo" had more Hawaiian locations than this film. Apparently shot on a puny budget, this movie highlights Hawaii's broken-down dive shops, gas stations, and cheapo hotels. Zulu -- later to star as Kono in Hawaii-Five-O -- appears as Thinnes' lumpy, inept sidekick, while France Nguyen models the Jenny Craig diet gone horribly wrong. Others sharing the flickering screen include a drunken Richard Harris knockoff, a George Takai imitator, a not-so-smart hit-man with sprayed-on Sansabelt slacks, and the villain "Tree", sporting a veddy British accent. You can pretty much figure out the plot halfway through the opening credits, but relax--just enjoy the giddy mediocrity of this 70's movie-of-the-week.Whenever I think of this movie (and I think of this movie often), I catch myself humming the theme, written for flute and tuba...no one knows why. Trivia note--Diamond Head was directed by Jeannot Szwarc, one of three contract directors at Universal who would go on to make much bigger films, in his case Jaws 2. The others were John Badham (War Games), and a young fellow named Steven Spielberg...

Think of this pilot as "Hawaii Five-O Lite". It's set in Hawaii, it's an action/adventure crime drama, lots of scenes feature boats and palm trees and polyester fabrics and garish shirts...it even stars the character actor "Zulu" in a supporting role. Oh, there are some minor differences - Roy Thinnes is supposed to be some front-line undercover agent, and the supporting cast is much smaller (and less interesting), but basically the atmosphere is still the same. Problem is, "Hawaii Five-O" (another QM product) already existed at the time and had run for years. It filled the market demand for Hawaii-based crime dramas quite adequately. Code Name: Diamond Head may have been intended as the heir to H50 as the older series eventually dwindled away...but it comes across as a superfluous, 2nd rate copy. It doesn't suck, but it's completely derivative and doesn't do anything as well as the original.There is some decent acting talent involved here. Thinnes is an old pro, and he gives the role his best shot, and he isn't bad. But Thinnes is only as good as his material and his director. Ian McShane is in here as an evil spy master named "Tree", and McShane tends to be the most interesting actor in any scene he appears in. But he's phoning his part in here. Frances Ngyuen is reasonably exotic looking, but her astounding skinniness, opaque features, thick accent and wooden delivery aren't the stuff of which dreams are made. Relying on her to supply the 'romantic interest' for Thinnes was probably the series' biggest mistake. At least for for a series aimed at white audiences brought up with Marsha Brady and Peggy Lee as our love goddesses. Give her another 30 lbs and a year with a dialog/voice coach, and she might cut it. Zulu is, well, his usual self - enjoyable in bit parts, but he isn't a person who can carry a feature by himself. In addition, the plot and dialog are strictly by-the-numbers, with nothing to distinguish them from any other Quinn Martin production. And by this point, the American TV audience had seen a whoooole lot of QM productions....I think "CN: DH" was one too many, and it sank without a trace. It wasn't the really the actors' fault, and I hope they walked away from this with a decent paycheck and one more entry on their C.V.s. MST3000 revived this for their treatment in their sixth season, and they had a lot of good natured fun with it. Worth seeking out in that version if you enjoy the MST approach to movie japery and lampoon, but I can't imagine anyone caring about this pilot for any other reason.
