Also known as ''Il Raggio Infernale,'' this Italo-Spanish spy {{film}} was one of the many to ride the wave of [[Film/JamesBond Bond]]-style knock-off spy thrillers in the [[TheSixties '60s]] and [[TheSeventies '70s]]. The plot, such as it is, follows the adventures of American super spy Bart Fargo as he chases down the kidnapped professor Carmichael, creator of the eponymous death ray (which, the professor must stress, was only created to be used for "peaceful purposes..."), and save him from a [[NebulousEvilOrganization poorly-defined evil organization]] which doesn't share the professor's...unique world view. Following the trail (and bouncy soundtrack) from Italy to Spain, Fargo must contend with the usual assortment of spies, FemmeFatale and one really, ''really'' violent UsefulNotes/AbrahamLincoln (trust us on this one) in order to make the world safe for all peace-waging death ray-wanting countries everywhere.

!!This film provides examples of:

* BaldOfEvil: Inverted; the guys who kidnapped the professor are the only ones in the room with full head of hair.
* BigBad: [[spoiler: Carver]] whoever the hell that is.
* BottomlessMagazines: Averted so thoroughly that watching Bart Fargo reload every minute or so becomes quite annoying. The film seems not to understand that after seeing him reload once or twice, the audience will assume that he continues to do so even without seeing it happen.
* TheCasanova: The movie tries to paint Fargo as this. Doesn't really work.
* CuttingTheElectronicLeash: Bart throwing his spy watch out the hotel window at the end. (See {{Narm}} below.)
* DeathRay: Naturally. [[InsistentTerminology For peaceful purposes]].
* DevelopingDoomedCharacters: The briefing about the peaceful Death Ray, and the lead up to it.
* DisposableWoman: [[spoiler: Mrs. Carver]]. She doesn't even get a first name. Hell, it's arguable if we can even be certain she's [[spoiler: actually married to Carver at all]].
* DeathTrap: The villain's lair at the end has machine gun cameras mounted on seemingly every surface throughout a ''very'' narrow hallway, yet Fargo somehow manages to take down every one without so much as a scratch.
* TheDragon: Frank, the Andre the Giant/Michael Caine-looking guy.
* {{Eagleland}}: At least, an Italian take on an American superspy, even giving him as "American" a name with "Bart" as a first name and "Fargo" as the second.
* FollowTheLeader: One of many, ''many'' films to try and ape the spy-craze of the the '60s.
* HeelFaceTurn: Al.
* HeroicBystander: Lucille. Most people might have an issue with random guys dropping through their skylights and being chased by guys with guns. Not her.
* IdiotBall: Fargo has a perfect shot at the escaping Al at one point in the film. [[AlternativeCharacterInterpretation For some reason,]] [[FoeYay he doesn't take it.]] Played straight at the end with the bad guys though; [[MoreDakka bless 'em for trying.]]
* IneffectualSympatheticVillain: [[ChewToy Al]]. To the point where even the ''hero'' takes pity on the poor bastard.
* LeitMotif: Bart Fargo's is the catchy "Badupadupadada".
* {{Mooks}}: By the caseload; on both sides, to boot.
* MoreDakka: Disguised as antique wall fixtures, for that extra bit of class.
* NotableOriginalMusic: Much of the music in the movie sounds a lot like Herbie Hancock's ''Watermelon Man'' and the catchy "Badupadupadada" for Bart Fargo's LeitMotif.
* PunchClockVillain: Poor Al really seems hate being on the low-rung of his organization's hierarchy and seems really keen on taking up Fargo's offer to get him out of it. [[spoiler: Poor, poor Al.]]
* RayGun: The Death Ray, which was built for [[SarcasmMode *cough* peaceful purposes *cough*]].
%% Zero Context Example; please add details if you're going to re-add this trope:
%% SatelliteLoveInterest
* TheSixties: Depressingly so, in Italy. The film just screams ''Casanova '70''. Which is odd, since it was filmed in Spain.
* SoundtrackDissonance: See EarWorm, above. This movie has some of the bounciest damn chase scenes you're ever likely to find.
* SpyFiction: Uh huh.
* TorosYFlamenco / OliveGarden: It's hard to figure out where exactly some of the locations are supposed to be, except for the scenes obviously set in Barcelona.
* TooDumbToLive: Al. He charges out from behind cover during a running gun battle for no apparently sensible reason.
* TuxedoAndMartini: Well, more like "Business Casual," but it fits the mold closer than Stale Beer (Bart seems to prefer Cointreau, incidentally), what with all the explosions and gunfire and the titular death ray.
* WhatHappenedToTheMouse: Whatever happened to Frank? Fargo's fighting him in a room, then it just cuts away for some reason.
