Continuity mistake: The sun sets in different directions with respect to the same view of Lord Farquaad's castle.
Continuity mistake: When Shrek and Lord Farquadd are talking about the swamp after Shrek has just beaten all of his knights, the flags move across the wall between shots.
Continuity mistake: When Shrek walks out of his house and finds the fairytale creatures, you can see the three fairies go into one of the tents that were set up. The shot goes back to Shrek for a minute and then goes back towards the crowd and the fairies are back in the place that they were before.
Continuity mistake: When Shrek is brushing his teeth, the mirror breaks. Later, when he returns to his swamp, the broken pieces are different.
Continuity mistake: When Shrek sits to eat his meal he has a slug on the left-hand side of his plate facing towards him. When he is invaded by the Three Blind Mice the slug is suddenly facing the other way.
Continuity mistake: When Shrek and the donkey are looking at the stars, in one shot Orion's Belt (three bright stars in a row) is right next to the moon, but in the next shot of the stars it's not.
Continuity mistake: At the end of the movie, the bouquet of flowers that the dragon has in its mouth switches sides. At first it's on the same side as donkey, then jumps to the other side in the wide shot.
Chosen answer: This is most likely because "broad" isn't too nice of a word, and children of any age could watch the trailer. Parents wouldn't want their children to copy inapropriate language, obviously.
