Continuity mistake: Stan asks his mum for money to go see the new T+P film. Through the door you can see the Post Office directly oposite. However, in the shot of him looking at the town earlier there is nothing opposite the Post Office. (00:00:50)

Continuity mistake: During the "La Resistance" song, Gregory is singing with the other kids in on group and Cartman, Stan and Kyle are singing in another group. However, as it shows the kids, Satan, the mothers against Canada and the fathers, Cartman, Stan and Kyle and the other kids are all together. They couldn't have been in the group with the other kids the whole time because another kid has appeared next to them. (00:50:50)

Continuity mistake: In the movie theatre, the kids' heads are below the back of the seats. However from the back view, their heads are above the seats. (00:05:40)

Continuity mistake: When Stan goes to Kenny's house, there is a fridge next to it on the left hand side. By the time he knocks on the door the fridge has disappeared. The fridge then reappears when Stan and Kenny leave the house. (00:01:45)

Continuity mistake: In the cinema hall, when we see the South Park kids before the movie starts, you can see what looks like a baby, who we can presume is Kyle's baby brother, 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 the baby has disappeared. After the gang leaves the cinema 3 hours later, the baby reappears and is seen dangling on Kyle's arm. (00:04:50)
Answer: Some versions of the film (VHS in Australia for one) contain the reference to the letter. Terrance: "Well, f*** my a** and call me a b**ch. I just got a letter." Phillip: "A letter from who, you sh**-sucking co**master?" Terrance: "It's from your mother." Phillip: "My mother sent YOU a letter? What's it say?" "Terrance: It says, 'Dear Terrance, please don't ever tell my son that I licked your hairy b***s.'"
