Visible crew/equipment: When Eggsy is in the car yelling at his mum's boyfriend and the windows start to go up, you can see a man's head next him on the floor.
Kingsman: The Secret Service (2014)
1 visible crew/equipment mistake - chronological order
Directed by: Matthew Vaughn
Starring: Samuel L. Jackson, Colin Firth, Mark Hamill, Taron Egerton
Factual error: When the barracks are completely flooded, Eggsy uses his bare fist to punch through a large two-way mirror to escape. The fact is that any glass (or plexiglas) thick enough to contain hundreds (or thousands) of tons of water without bursting would be as impenetrable as concrete to Eggsy's bare fist. He would need a chisel-tipped jackhammer to penetrate such a mirror.
Harry Hart: There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self.
Trivia: Colin Firth did 80 per cent of his own stunts in this film.
