''Touch of Evil'' (1958) is one of the last and one of the greatest examples of FilmNoir, written by, directed by and co-starring Creator/OrsonWelles.

Welles plays Captain [[DirtyCop Hank Quinlan]], a fat, ugly and sad corrupt police officer. The black-and-white film also features Creator/CharltonHeston as [[KnightInSourArmor Mike Vargas]], a Mexican narcotics agent on his honeymoon, Janet Leigh as his bride, and Marlene Dietrich as Tanya, a cigar-smoking Mexican gypsy brothel owner with huge beautiful eyes.

The film begins with an exploding car killing a powerful businessman, witnessed by Vargas and his new wife Susie on the Mexican border. Claiming joint jurisdiction (as the bombing may have been placed in Mexico), he works his way into the investigation headed by Quinlan. Quinlan quickly sets his beady eyes on a lowly Mexican employee that had a grudge with that businessman (the employee wanted to marry the businessman's white daughter). When Vargas notices that some of the evidence found by Quinlan's loyal partner Menzies was clearly planted (but can't prove it), Vargas starts questioning Quinlan's case history. But while this is all happening, Susie Vargas is left all alone at a creepy hotel where some gang members that Vargas is after is holed up as well... and Quinlan starts making a few calls to the gang's boss about what to do with that lonely newlywed...

The story goes that producer Alan Zugsmith offered Welles a pile of scripts to direct and Welles asked for the worst one (based on pulp novel ''Badge of Evil'') to prove that he could make a great film of a bad script. Such a thing isn't really possible, but Welles did revise the script into something much better, and filmed that. Unfortunately, the theatrical cut [[ExecutiveMeddling didn't resemble Welles' vision.]] Decades later the film was re-cut twice - first in 1976 and again in 1998 when a letter Welles wrote full of instructions on how the film was to be put together (which Creator/CharltonHeston himself reportedly had been in possession of for years) was used to reconstruct the film as close to Welles's vision as possible.

!!This film provides examples of:
* TheAlcoholic: Quinlan doesn't drink often, but when he does he gets absolutely ''plastered''.
* AuthorAppeal: Welles had been a huge fan of Dennis Weaver's work on ''Series/{{Gunsmoke}}'' for years, and wrote his part specifically so he could have the chance to direct him in a movie. Similarly, Marlene Dietrich's role was [[ThrowItIn added during filming]] because she and Welles were best friends and she wanted a part in the movie.
* AsLongAsItSoundsForeign: Charlton Heston's attempts to speak Spanish are pretty laughable. When the sentence is short, he'll give it the old college try, but his gringo accent betrays him (e.g. "¿Puedo usar el teléfono?" in Sanchez's apartment). Most of the time, though, he'll just mumble something deliberately inaudible and end it with an appropriate Spanish word. (e.g. "Murmurbliggleblamurmur derechos aquí" in the same scene, presumably explaining to the suspect that he has no jurisdiction.)
* CaliforniaDoubling: Sorta. While it depicts life on the California/Mexico border, most scenes were filmed in Venice, California about 140 miles away.
* TheCameo: Welles's old friend and former co-star Creator/JosephCotten makes a brief appearance at the bombing crime scene, as the coroner. ("Now you could strain him through a sieve.")
* CloudCuckooLander: The Mirador Motel Night Manager.
* CreepyCrossdresser: [=McCambridge=] appears as an androgynous-looking gang member abducting Susie Vargas. Her big line? "I like to watch."
* DiesWideOpen: Grandi when he is strangled.
* DirtyCop: Quinlan has been framing suspects for years.
* DodgyToupee: Grandi loses his at one point.
* EpicTrackingShot: The opening consists of one long tracking shot, which is considered by film aficionados to be one of the best ever.
* {{Fanservice}}: Janet Leigh laying on her bed (both when talking to Vargas over the phone and later, when sleeping). In a figure-hugging teddy, sans skirt. [[ShesGotLegs With her long and beautiful legs featured prominently.]]
* FilmNoir: Considered one of the last great ones from that era.
* FramingTheGuiltyParty: "How many did you frame?" "Nobody that wasn't guilty!" And in fact it turns out that the bombing suspect actually was guilty.
** Subverted with Quinlan's effort to get the Mexican drug gang to kidnap an innocent Susie Vargas, then kill the gang leader and frame the drugged Susie for that murder.
* GreyAndGrayMorality: Quinlan only frames criminals he thinks are guilty, and Vargas is only able to stop him when Menzies -- whom Quinlan had previously ''taken a bullet'' for, causing his limp -- agrees to betray him. Vargas for his part sees the grayness of policework
--> '''Vargas''': ''"A policeman's job is only easy in a PoliceState."''
* GutFeeling: "I wonder, what makes you so very sure it was dynamite?" "My leg."
* HitlerCam: Orson Welles was fond of this trope, going all the way back to ''Film/CitizenKane''. Here he uses it for the scene where Quinlan, Vargas, and others are gathered around the body of the murder victim. Notably he does not use it when showing Menzies, Quinlan's faithful sidekick.
* ICantBelieveItsNotHeroin: There is ''actual'' heroin as well, but...
-->'''Gang Leader''': We've scattered more reefer stubs around.
-->'''Grandi''': You kids didn't use none of that stuff yourself, anh?
-->'''Ginnie''': Think we're crazy?
-->'''Grandi''': Nobody in the Grandi family gets hooked, understand? That's the rule.
* IncrediblyObviousBomb: So obvious that the lady passenger in the car complains about a ticking noise.
* IOweYouMyLife: Menzies, to Quinlan.
* IronicEcho: "That's the second bullet I took for you, partner..."
* KnightInSourArmor: A long time ago, Quinlan was unable to prove the guy who killed his wife committed the crime. It drives him to start framing guys he's convinced by the pain in "my leg" are guilty.
* MadeOfPlasticine: "Once he ran this town. Now you could strain him through a sieve."
* MalignantPlotTumor: The original bombing investigation is almost completely forgotten by the end of the film in favor of Vargas' attempts to bring down Quinlan. The ending shoehorns in a line that the guy Quinlan framed really was guilty after all.
* NotEvenBotheringWithTheAccent: One of the most infamous examples, Welles assured Heston he didn't have to do a Hispanic accent for his FakeNationality role as the Mexican Narcotics officer Vargas, cobbling together unofficial backstory saying that Vargas lost his accent due to his travels outside of Mexico and working with Caucasians.
** It must be noted that there are no Mexicans in the cast. Grandi is played by an Armenian actor Akim Tamiroff and the Gypsy Fortune teller played by Creator/MarleneDietrich who doesn't even hide her famous German accent. The film is set in a border area between America and Mexico and actually shot around Venice Beach, Los Angeles with very distinct, identifiable architecture. It's not a realistic film by any means. In any case, the idea of actors affecting accents for their part wasn't all that common among Golden Age actors like Charlton Heston or Welles, who weren't into the later dominant style of MethodActing.
* TheOner: The opening sequence features one of the most famous continuous camera shots. Also, at the shoe clerk's apartment, there is a ''long'' continuous shot where the camera moves from room to room following Heston.
* ReCut: A "director's cut" of ''Touch of Evil'' based on a contemporary Welles memo of how he wanted the film to be is now available on video.
* RedRightHand: Inverted in a way. Quinlan has a limp and says he can tell when someone is guilty because his leg begins to hurt. However, the reason he has a limp is because he took a bullet for his partner.
* SweaterGirl: Janet Leigh manages to provide {{Fanservice}} while portraying a respectable woman by wearing some very, very tight sweaters.
* VillainousBreakdown: Hank's descent after his last meeting with Grandi.
* VillainWithGoodPublicity: Hank Quinlan became a very well-respected policeman through careful evidence tampering. In the end, it even turns out that the man Quinlan was trying to frame in the film ''was'' guilty, giving him the epitaph, "He was a great detective, but a lousy cop."
* YourDaysAreNumbered: When Quinlan visits his friend Tana the fortune teller. He asks her to see his future. Tana warns him "You haven't got any... Your future is all used up."
