Continuity mistake: In the scene where Madame Zeroni is explaining to Elya Yelnats about the curse that will be bestowed upon him if he doesn't carry her up the mountain after presenting the pig to Myra's father, her blouse is a blue button-up with gold stripes and no collar. Then the camera looks at Elya, and then back at Madame Zeroni. When it looks back at Madame Zeroni, you can see that her blouse is now a gold button-up with a collar.
Continuity mistake: When Mr. Sir gets angry at the boy who said, "What happened to your face?" he asks the campers if he looks good and you see D-Tent sitting in the upper left hand corner, everyone is sitting down. In the close up of D-Tent, X-Ray and Armpit are standing then. In the next shot with Mr. Sir, you see Armpit and X-Ray going to sit down. Then back to Mr. Sir, you see X-Ray standing.
Trivia: In the last few scenes of the movie you see the Attorney General (he's the man with the cowboy hat and round sunglasses) this man is also the Stunt director/organiser. He contributed a lot to the film as all the stunts where organised by him so the director decided to give him a small part as a way of saying thank-you.
