Continuity mistake: The red Ferrari moves 2 feet to the left after being pulled over. (00:30:55 - 00:32:20)
Continuity mistake: Jon is scarfing down a burger at the Tommy's kiosk while Ponch is jerking off in the bathroom. He gets a mess of mustard all over the shirt, down to the belt, and to the pants. The pants stain vanishes right away for the remainder of the scene (but shows up later in another scene). (00:35:40)
Continuity mistake: When Jon talks to his ex in the pool, she wringing her hair in a ponytail in front of her left shoulder, several times, but in the reverse shot it's like it never happens, the hair every time is still and not being pulled or raised. (00:35:00)
Continuity mistake: When Jon saves Ponch from the truck, the truck crushes the bike under its front tires, which suddenly become another set of wheels in the shot right before the big explosion. (00:43:20)
Visible crew/equipment: When Jon passes by Ponch who roadblocked the street ineffectively, on the front of his bike you can see the reflection of the camera rig. (00:42:00)
Continuity mistake: As Jon punches Ponch, he does not mess up his headset and glasses much, if at all. But the following closeup of Michael Peña has him all discombobulated, with crooked glasses and the mic up his nose for added comedy value. (00:43:35)
Continuity mistake: Ponch escorts the senior citizen back to his Ferrari, but Jon tries to jerk him back to the police car. During this back-and-forth exchange, the natural light of the scene changes in a blink. (00:32:20)
Continuity mistake: When Castillo shoots through his own partner, he falls down with his butt roughly where the yellow line on the asphalt is. When he is shown again, he's lying down some meters away. (00:06:40)
Continuity mistake: When Jon Baker wakes up, the on screen caption says "8.26 AM." Then Jon staggers his way to the bathroom, passing in front of the clock which shows 8:05. (00:01:00)
