Plot hole: When Leo, Gustav and Himmel are driving through Miami looking for Pest, Gustav notices that the tracking device that was put in Pest's underwear shorted out because of how much he was sweating. An earlier scene showed that Pest jumped off a boat in the middle of the ocean and swam to Miami. Since the tracking device was in Pest's underwear the whole time, it should have shorted out the moment he jumped into the water leaving Pest safe and Leo, Himmel and Gustav driving around aimlessly.
Continuity mistake: When Pest leaves the bathroom at the beginning of the movie, you can see a towel wrapped around his waist. The shot goes to a full body shot and you see him whip the towel off. The next shot is of his knees down and the towel is back.

Continuity mistake: When the guy puts the tattoo on Pest's face, the tattoo on his face is different from what was shown before it was put on.
Audio problem: In the Scene where Pest climbs the ladder to the pool party he spits out water and you hear "Ginger, no contest" without him moving his lips.
Visible crew/equipment: When the Pest is trying to hustle the crowd as a blind man, there is a Hispanic kid in the background watching. He starts making faces and throwing up hand symbols at the camera. He was either a kid who sneaked onto the set or an extra who decided to get noticed.
Continuity mistake: When the pest gets hit in the head by the basketball, it shows a shot of the kids where one of them has his shirt up where you can see his stomach, but the next back view of them, it's pulled down more.
Continuity mistake: In the beginning when Pest is about to exit the house, you can see that the door is a solid six-panel door. But when he exits, the door has a fan-light glass insert. (00:04:20)
Audio problem: When Pest slaps his black friend in the car, the last slap does not synch up with the sound of the slap.
Other mistake: Before Pest is getting hunted, the hunter makes a toast, there are two mistakes here, one is that the champagne glasses fluctuate the amount that is in them, and in a couple cut scenes you'll see that it is raining, and in others it isn't.
Continuity mistake: When Pest is telling his friends about the scams, you see a front shot of him where his glasses are down below his eyes, but next shot which shows from behind, you can see that his glasses are over his eyes.
