Continuity mistake: The amount of damage to the car Kincaid is driving changes drastically between shots. Most noticeable right after he kills the motorcycle driver he does a jump and the hood and headlights break off. It cuts to the others running through the streets for a few seconds, then cuts back to him as he passes under a bridge - the front of the car is almost completely repaired as he is under the bridge, then changes back to damaged after he leaves. (01:30:45)
Continuity mistake: When Mildred and her son pull up in the station wagon, there is a drink thrown at the car that hits the windshield.

Continuity mistake: At the end of the movie when Eggsy and Hart are talking before the wedding, Hart's eye patch changes from the left side to the right.

Continuity mistake: During the drunken gymnastics young Miss Langford is doing to the delight of the paparazzi, she is wearing transparent pantyhose for the most part of the scene; you can see it during the cartwheels with the panty shot, and with the feet close-up. However her legs and feet are bare when the camera shows a stuntwoman leaping over the gifts and crashing into the tree (probably they didn't want to tear the stockings with that landing). (00:02:30 - 00:03:55)
Continuity mistake: Gene and High Five are using costumes to hide, and Gene's costume leaves a spike in his face, but when they put the costumes down and run around the corner there is nothing on his face.
Continuity mistake: Jon fell over on the rainy day and he can't get up. When he blindly goes for his phone, clothes he had on the bedstand (and that he could have put on) disappear between shots, and when he knocks the magazine off the bedstand and the pillow underneath, there is no trace of the tube that is instead perched on it later in the scene. (00:46:10)

When the camera is on the principal as he is walking into the room, there is nothing on Rob's shoulder, but in the next shot, the strap on Rob's bag has suddenly appeared there. Then in the next shot, he is shown placing the strap over his shoulder. (00:01:35)
