Editing Cobra (1986 film) (section)

===Filming===
Originally, ''Cobra'' was supposed to be filmed in Seattle, climaxing with a motorcycle chase scene on a [[ferry]] between the islands. Even though everything was prepared to start filming the final theatrical version of the scene at night, Stallone demanded the ending be changed because of the mosquito problem at that time, which would have made night time filming very difficult to endure.

The supporting cast and extras were forbidden from talking to Stallone on set.<ref name="MovieGeeksUnited">{{cite AV media| url = https://www.youtube.com/watch?v=eBJlfp25vUM | title = Summer of 1986: COBRA | quote = <!-- at 39:00 minute mark -->with cinematographer Ric Waite and costar Brian Thompson | work = Movie Geeks United!}}</ref>

At one point during filming, Stallone complained to cinematographer Ric Waite that they were falling behind and that he needed to push his crew to work harder. Waite responded by telling Stallone that the delays were due to his fooling around with Brigitte Nielsen and showing off for his bodyguards. Although Stallone was shocked that somebody would talk to him that way, he cleaned up his act and behaved more professionally, although he returned to his old egocentric behavior a few weeks later. Waite later said in an interview that, despite his huge ego, Stallone had a great sense of humor. He said George P. Cosmatos would have made a great producer, but he was a terrible director.<ref name="MovieGeeksUnited" />

During a stunt scene, driver [[Kerry Rossall]] and another stuntman were injured after Rossall intentionally crashed a van into a wall. Nielsen was nearly hit by the van during a previous take.<ref>Brouwer, Alexandra (1990).

For the Night Slasher's monologue in the lead-up to the final fight, Brian Thompson did the scene with the script supervisor standing in for Stallone, who was busy watching a basketball game on TV.

The custom [[Mercury Eight#Third generation (1949–1951)|1950 Mercury]] driven by Cobretti was actually owned by Sylvester Stallone. The studio produced stunt doubles of the car for use in some of the action sequences, such as the jump from the second floor of the parking garage. The production built three "Cobra cars" for stunt work. Although they were identical on the outside, their moving parts were designed for specific sequences, involving high-speed swipes with other vehicles, 180-degree turns, jumps, and 360-degree spins.<ref name="afi">{{cite web |url=https://catalog.afi.com/Catalog/moviedetails/57290 |title=Cobra |website=AFI |access-date=February 28, 2016 }}</ref><ref>{{cite web |author1=MARIELENA HATZIGIANNIS |title=Sylvester Stallone reportedly reunites with stolen car |url=https://www.cbsnews.com/news/sylvester-stallone-reportedly-reunites-with-stolen-car/ |website=CBS News |date=March 30, 2011 |quote=he designed the car to fit his role in the movie, and that the car is worth around $250,000}}</ref>

The knife used by the Night Slasher was made for the film by knife designer Herman Schneider.<ref name="afi" /> Sylvester Stallone asked Schneider to create a knife that audiences would never forget. Cobretti uses a custom [[Colt Gold Cup National Match 1911]], modified to chamber [[9×19mm Parabellum]]. Later in the film, he uses a [[Jatimatic]] submachine gun.<ref name="afi" /><ref>{{cite book |last= Hunter|first=Stephen |author-link= Stephen Hunter|date= 1995|title= Violent Screen: A Critic's 13 Years on the Front Lines of Movie Mayhem|url= https://books.google.com/books?id=tiKjMVaU0VwC&pg=PT251|publisher= Bancroft Press|quote=...Sylvester Stallone's “Cobra,” which features numb performances by the actors and brilliant performances by a Finnish Jati-matic 9mm submachine gun with a laser sighting system...|isbn=9780963537645}}</ref>
