Goofs

Camero has dark blond hair throughout the film except for one brief shot when her hair is dark black when she is about to drop a cigarette lighter to set Trixie on fire. It was an insert shot filmed months after production ended when America Olivio dyed her hair for a different film role that she took immediately after filming on this picture ended.

When "Sister" Camero gets stopped by the police at the convent (1:09:xx) she has two guns strapped on shoulder holsters. When a cop first takes her left gun, there does not seem to be a gun in her right holster, and when he proceeds to take her right gun, the left gun in back (or maybe still) in the holster, indicating that the takes of the gun removals were reversed.

Trixie claims that the sword is forged in the 16th century, and then continues to say that "it has seen battles won and empires fall for over 600 years." Which does not add up since the movie seems to be set around early 21st / late 20th century, so it could be no more than 500 years old.

Trixie's eye makeup keeps changing color. It is usually a shiny, smoky gray but during the entirety of the desert sequences (which take place on the same day), the color switches. Colors include: dusty pink, light gray, dark gray, gray with beige and an almost black color. The only consistency is her black eyeliner.

At the end of the movie Trixie is holding a samurai sword and she calls it 'naginata'. Naginata is actually something more like a spear, while samurai sword is called Katana.

Hel comments that the coordinates that Trixie saw on the map in Gage's room might be vector coordinates. They are more likely simple longitude and latitude as they end with 'N' and 'W.' Converting the location in the simplest way gives 35° 34' 08.81" N by 17° 19' 00.90" W, which locates it in the North Atlantic ocean approximately 600 miles west and 100 miles south of Gibraltar.

While Kinki is "playing" with Trixie, Camero and Hel are digging, and they dig for a while before their shovels hit metal and they find the hatch. However, there's no hole - the hatch appears to have no more than a sprinkle of sand on it.

In the prison scene Camero is doing pull-ups but none of her muscles are flexing. She doesn't even try to make it seem realistic, making it obvious someone or something is just hoisting her up and down.
