Here is a movie with no redeeming values. It's not interesting. It's not funny. There's no compelling cinematography. The musical score is blah. The script is awful. The acting is bad. The action scenes are meh. Jan Murray, a former SS Nazi, wants Paul Mantee (Dagger) dead. That's the plot. There are several attractive women that are scantily dressed at various points in the film, one of which is Murray's secret weapon under his control. Richard Kiel (Jaws from Bond) makes a couple of appearances as another Murray henchman but is given almost nothing to do. No reason to watch this - no entertainment value.

In general, I prefer European films to those made in USA, are superior to all intents and purposes. But after seeing this film and then reading those 4 negative reviews here on IMDb, I must write in this: I recommend to those who wrote the 4 reviews, to watch some eurospy movies (James Bond type films made exclusively in Europe, excepting United Kingdom), most are much worse than this film (I saw over a hundred). And now, my own review: This "A Man Called Dagger" (1968) has much in common with the original James Bond movies. First, the music signed Steve Allen, sounds almost note for note with the original theme signed by John Barry. Then, Richard Kiel, before playing in "The Spy Who Loved Me" (1977) and "Moonraker" (1979). The script, written after the Bond recipe. Richard Rush is a director with a keen sense of humor. As Paul Mantee, who plays Dick Dagger, some kind of a restrained, discreet and, especially, very peaceful, non aggressive, James Bond. Jan Murray is not bad at all as the villain Rudolph Koffman / Hans Leitel and all the actresses, Terry Moore, Sue Ane Langdon, Eileen O'Neill, Maureen Arthur, are funny. Everything is a fine parody.

I think this is the worst movie I've ever seen. I would say that I couldn't imagine a worse one ever coming along in my lifetime, either, except that Steve Allen did the music and Steve Allen is never completely awful. One abject moment of creative bankruptcy that has remained in my mind all these years is when Dagger and one of the temptresses swap reminiscences of all the exotic places they have met before. Well, not reminiscences. Just the names of cities. Maybe by their acting they were supposed to load the names with meaning, but the turkey in your average grade-school Thanksgiving play does more acting than anyone in this whole movie...

Richard Rush is a good director, Paul Mantee is a first-rate character actor, and Eileen O'Neil is spectacularly beautiful besides being a very good actress. Put them together and what do you get? Junk.While low-budget doesn't necessarily mean low quality, in this case it applies. The film's cheapness shows through in practically every frame, and there's not much Mantee or Rush can do about that. With all of the film's many faults, though, there are two that it can't overcome--an incoherent script with holes you can drive a truck through, and an hysterically awful performance by comic Jan Murray. Murray plays a Nazi scientist trying to revive the Third Reich and take over the world from a wheelchair. His "research" for the part must have consisted of watching dozens of old silent movies, as his performance is a virtual carbon copy of the stereotypical nostril-flaring, eye-rolling, teeth-gnashing, hand-flailing ham acting from a cheap melodrama of 1915. After a while you find yourself yelling at the screen, "For God's sake, shut up!" It's almost as bad as watching a Madonna movie.If you're a fan of Paul Mantee (who did such a great job in 1964's "Robinson Crusoe on Mars") or Richard Rush ("The Stunt Man") or just want to stare open-mouthed at the gorgeous Eileen O'Neil, then go ahead and rent this movie. But do yourself a favour--turn the sound off.
