1 visible crew/equipment mistake
Directed by: Matthew Vaughn
Starring: Samuel L. Jackson, Colin Firth, Mark Hamill, Taron Egerton
Factual error: When the barracks are completely flooded, several of the trainees shove shower hoses down the toilets for an "unlimited supply of air" (Merlin describes it as "simple physics"). However, that old fireman's trick is a technique for surviving dense smoke, which is not under fluid pressure. In the barracks flooded 9 feet deep with water, the pressure would be so enormous that it would easily gush straight down the toilets in a powerful torrent, eliminating any "unlimited air supply."
Harry Hart: There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self.
Trivia: Eggsy needs the code for the prison door that holds Princess Tilde. The code given is "2625." This spells out the word "anal" on a telephone keypad.
