Other mistake: The first victim of the mask in the series falls back against crates that must be made of dry leaves, since all it takes is for the body to lean against them to utterly shatter them. (00:18:55)
Other mistake: They keep saying the taxi cab is 20 years old, but that cab is brand-new in the episode.
Other mistake: When Matt and Claire are on the roof and Matt says "A dead guy, a guy I witnessed burn to death," Charlie Cox's natural English accent slips through. (00:41:35)
Other mistake: When Happy goes to see if the backhoe will work to finish freezing the water she says the hoses are damaged. The hoses she indicates as damaged are the ac lines and hydraulic lines that hydraulic oil flows through - she does not even look at the water hoses. (00:18:40)
Six Forgotten Warriors Chapter 4: The Six Fight Again - S5-E5
Other mistake: The news footage of the elderly Six American Heroes being attacked by the Insidious Six is merely clips from the previous episode.
Other mistake: In the English DVD subtitles Sebastian says, "In direct combat, they're is no warrior equal to the Red Series." "They're" should be "there". (00:24:00)
Other mistake: The opening scene shows a captive with a hood over his head being dragged barefoot along a long driveway by two men. His feet are dragging over the ground. He is then strung up by his hands, and when they show his feet, there is not a scratch on them.
Other mistake: It is established that Drs. Quest and Hartman speak the Po-Ho's language, but when they are captured, Dr. Hartman is translating to Dr. Quest how the Po-Hos are going to torture them.
The Pyramid of Darkness: Part 1 - The Further Adventures of G.I. Joe - S1-E1
Other mistake: Mutt reads the card about the "fatal fluffies." He says "I'm sure you'll enjoy their deadly secrets", but the card reads "I'm sure you'll enjoy their amazing "split" personalities."
The Grim Reaper Wears a Teflon Coat - S1-E5
Other mistake: For the first few episodes of this show, Rhodey is voiced by James Avery. However, there are two scenes in this episode with Rhodey providing voiceover, and you can tell he is voiced by Jim Cummings. Presumably Avery wasn't available to record the dialogue for these parts, so they just went with Cummings instead. (00:10:36 - 00:18:06)
Other mistake: The woodchipper is shown cutting wood, but is squeaky clean when the golfer sticks his hand in it to get the ball out.
Other mistake: When Rebecca is telling Dorn about Etienne's death, she explains that his room was right above the garage and after the explosion she "tried to go in, but the room was gone." Yet at the end of the episode when Louis goes into Etienne's room, it is fully intact, including pictures taped to the wall.
Who Are You? - S1-E4
Other mistake: Magpie is surprised by the guard at the beginning of the episode; the guard is running in the room, hand going for the gun. After a cut to her with close-up on her elaborate fetching of the bombs with her awkward nails, the man is standing still, hand down his leg, only then going for the weapon. Two bombs fall at his feet, one per foot, touching the feet directly. Obviously he just looks at what they are instead of jumping back, and they explode in a single mushroom cloud CGI explosion, to his left. (00:01:10)
Other mistake: After they arrive in Marina Bay the pink ranger is wearing the red ranger's jacket.
