Continuity mistake: After Ron throws the burrito at the biker the exterior shot of the car shows he is in the middle of the three lanes. When it cuts to his reaction shot you can see he is now in the left lane. After showing the biker in agony we see Ron getting out of his car in the middle lane.
Continuity mistake: Right after Ron throws Veronica over the desk after she makes fun of his hair, she jumps on his back, and pins him to the floor. In the first shot of the floor, a purse is seen on Ron's right, but the in the next shot of the floor (where she picks up the mace) the purse is on his left.
Continuity mistake: Before the big brawl between the rival news crews there are a number of shots where the sun is nearly setting and a second or so later will be right back up. The most notable one is just after Ben Stiller's Spanish language crew arrive there is an aerial shot with the sun very bright. In the next shot of Tim Robbins the shadow has become much more noticeable.
Continuity mistake: Early in the movie, as Ron Burgundy is talking with his dog at his apartment, pay close attention to the suit jacket on the back of the chair. As the camera shifts between views of the dog and Ron, the coat moves around. In the final shot, when the dog jumps off the back of the chair, the coat is in yet a third position.
Continuity mistake: In the scene when there is a question mark written on the teleprompter and Ron says, "I'm Ron Burgundy?" you see a shot of the teleprompter and the question mark is visible. However, what's written on the teleprompter and what Ron says before this are two different things. Ron says something about the panda, but the teleprompter says something about a blind man and his pet falcon.
Continuity mistake: In the scene when Ron invites Veronica to the "gun show", after he has counted over 1000, he goes to put his shirt on. He reaches into the armhole and then it switches to a shot of Veronica and then back to Ron. In the next shot of Ron, he is reaching into the armhole again.
