Character mistake: When everyone starts counting down to blow up the Violet Dwarf, everyone starts at 10 downwards. Yet 40 seconds later, they are still counting down. (01:19:40)
Suggested correction: Its very common for movies and TV shows to do this. Just because they say 10 seconds doesn't they can't spend more time going through the thoughts in Fry's head.
Character mistake: The opening shot of the movie pans across a fence supposed to enclose the hunting reservoir of the royal family of the fictitious kingdom of Vespania. Judging by the sign on the fence, the official language of the country must be EngRish; the sign says "Land Demesne We knownothing [sic] about FIRE!", citing also as source for these cryptic messages the "internal secuLity act of 1950."
