Other mistake: When Special Agent Bloom arrives at the beginning of the film, there's a shot of Greenly spraying breath spray into his mouth and while he does this, he's bent over, but in the very next shot, he is standing completely upright.
Other mistake: The history in the world of this movie does not have to follow our own (after all, in Toriyama's creations we have dinosaurs roaming the Earth, and talking animals), however the opening narration talks about how "thousands of years ago" Piccolo bringing our "peaceful planet" and "the HUMAN RACE, on the BRINK OF ANNIHILATION." The movie is set in 2010-ish (Goku has a poster of the "Pazu United" football team, year 2010), and turns out from later dialogue that Piccolo is coming back after 2,000 years. The implausibility of a nearly world-ending global catastrophe happening barely 2,000 years ago and being completely erased from history (nobody remembers Piccolo and everybody laughs off the notion of an invasion around that time) is astonishing, but even admitting that, the opening crawl briefly shows warriors in full plate armor, definitely out of place for circa the first century AD. Everything about the narration leads to a very far back mythical pre-historic past, so when later it turns out it's" just" 2,000 years ago, it makes no sense.
Other mistake: When the Amazons interrogate Steve they don't know the meaning of the word "crap" yet they know one of the definitions of the word "rack."
Suggested correction: Just because they understand some slang, doesn't mean they should understand all slang.
Well if they're an ancient race then how do they know of the use of the word rack regarding female anatomy? One of them went out into the modern world and learned this? Hera tell them this? Maybe they got internet or a modern dictionary?
Well obviously they know stuff about the modern world. Diana could speak Dutch fluently, not Old Dutch either, but modern Dutch. So they do get information or else she wouldn't have known that. This would include slang.
Other mistake: Since the Doctor got her leg injury, every time you see her walk, she does so with great difficulty, yet after they blow up the terraforming plant, she's running away with no problems at all.
Other mistake: At the very beginning, the first cut to Mr Lapadite he has an axe in his hand, ready to strike (and we heard two strike sounds before), but there is no log to cut. (00:03:17)
Suggested correction: He is cutting the stump. We see him actively cut it too, not only ready to strike.
