Continuity mistake: In the cinema hall, when we see the South Park kids before the movie starts, you can see Kyle's baby brother Ike, sitting next to him to his right. However, at the part in "Asses of Fire" where Terrence and Philip are having a farting competition with a traffic police and after a couple left the cinema in disgust, the camera cuts back to the gang, but Ike has disappeared. After the gang leaves the cinema 3 hours later, Ike reappears and is dangling on Kyle's arm. (00:04:50)
