Revealing mistake: In the Kentucky church-massacre scene, Harry briefly scuffles with a man in a light blue sweater. Harry elbows him in the ribs, sticks a grenade in the man's pocket, spins him around and delivers a crushing blow to his neck, then hurls him head-first into a wall. Throughout this sequence, the man is obviously a live human being. However, a fraction of a second before he impacts the wall, he transforms into a life-size rubber dummy before our eyes, in mid-frame, without any obvious camera cut. This demonstrates the complexity of the scene - it is a digitally-edited collage of action sequences almost seamlessly strung together into what appears to be one long traveling shot.

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: Are we going to stand around here all day, or are we going to fight?
Trivia: Colin Firth did 80 per cent of his own stunts in this film.
Question: Harry told Dean he had enough information on him to have him locked up for life. What information was this?
Answer: CCTV surveillance and such like. And a possible kingsman informant embedded in the gang leaking incriminating info. Or police informer who reports to kingsman. Or, y'know, he was lying.
Answer: Details aren't given, but it seems that Dean is involved in local crime along with the gang that hangs around with him. Even if Harry is bluffing, and doesn't have specific proof, it is clear that he is abusive and he has the recording of him threatening Eggsy.
