Continuity mistake: Peppermint Patty can be seen in the same class as Charlie Brown and Linus, even though she says that her school has chosen her as a Foreign Exchange Student and is apparently unaware that Charlie Brown has been given the same honor.
Suggested correction: Peppermint Patty lives on the other side of town from Charlie Brown and Linus in America, so she does not attend the same school.
Continuity mistake: When Gort is fixing the wheel on the man's wagon there are brown leaves stuck to it. When the shot changes to behind Gort the leaves have suddenly vanished. (00:31:45)
Continuity mistake: When Mrs. Morgan notices the peppermints, they're individually wrapped. When she picks one out, they're unwrapped.
Revealing mistake: When Terrible Tommy has Rosa in an airplane spin her hair suddenly gets thicker and her legs get thicker, indicating this is Rosa's stunt double.
Continuity mistake: When Cole and the halfbreed duel with knives, the fabric they hold in their mouths as a tether keeps flipping over, meaning the end of the cloth hangs out the left side of the mouth, then the right, and left again - several times for both actors - even tho the fight is continuous and they make no moves that would change this.
Continuity mistake: When Ira and Glenda are discussing Nick, who is hiding under the bed, Ira briefly stands on Nicks right-hand pinky finger. After Ira has walked away, under the bed Nick grimaces while holding his left-hand pinky finger.
Visible crew/equipment: In the bar fight scene, the camera crew is visible right after Lefty hits one of the bar patrons.
Continuity mistake: Gus Soltic at the beginning of the movie pours ketchup on the eggs. When he's done, he moves away the bottle in one shot, but it's still vertical above the eggs in the next shot. (00:02:00)
Revealing mistake: At the end of the film, it's obvious the ground that Phil falls into is just some mats dressed up in fake snow.
Visible crew/equipment: When the main character and his family are first seen making their way to the train, the rightmost one in a row of three eerie blonde pageboy-haired children keeps looking into the camera. Generally, throughout the movie, there are plenty of instances of child actors looking into the camera, mainly young Malcolm (Lorenzo Aiello). (00:05:15)
Revealing mistake: In this very-low-budget but star-studded flick about UFO contactees and cattle mutilations, Jan Michael Vincent's semi-auto handgun runs out of ammo during a firefight after firing only 3 rounds (the slide locks open, indicating the magazine is empty). Without reloading or racking the slide, Vincent continues firing 5 more rounds; but we see again, in close-up, that the slide is locked open, indicating an empty magazine. (01:00:55)
Factual error: The Hillman Minx car seen picking up Brits at Conchin railway station is at least a 1945 model. The film is set in 1943.
Continuity mistake: Kenny must be fast. He's disguised as the female assistant at one point then minutes later he's disguised in the Groucho Marx costume.
Suggested correction: It's not a full costume. Kenny steals the mask and what looks like a small waistcoat (leaving even the hat). It's not implausible that Kenny made a quick change (probably after killing Ed) to formal wear (which isn't what Ed was wearing). After Ed's murder, Kenny-as-Ed appears briefly only from the waist up (showing only the stolen mask and waistcoat), and then doesn't appear again for quite a few minutes, more than enough time to change to the formal wear.
Visible crew/equipment: In the opening shot of the movie, several people (presumably the film crew) are reflected in the eye of the titular reptile. (00:00:15)
Continuity mistake: When Mickey gets into the '57 Chevy to "test drive" it, there is no gear shift lever on the steering column. The camera then shows him buckling his seat belt, and when it returns to the previous angle, there is that missing shift lever.
Factual error: In this poorly-researched film ("based on a true story"), Tom Horn lugs around a government-issue, lever-action 45.60 caliber rifle and even claims that he prefers the 45.60 because the ammunition is plentiful wherever he goes. However, there is no historical or biographical record of Tom Horn carrying and using a 45.60 rifle. In point of fact, the real Tom Horn's weapon of choice was the lever-action 30.30 rifle (a common range weapon of the day, often known as a "brushbuster"). When Tom Horn was arrested for murder in real life, he was carrying his 30.30 rifle, but a 45.60 cartridge was discovered in his pocket. This film fabricated its fictional plot around that 45.60 cartridge found in his possession.
