Continuity mistake: In 'Time and Punishment,' when Homer exits the basement, he discovers Bart and Lisa are giants, and he then screams and runs back to the "basement" - however the same door that leads to the basement seconds ago, now leads to a green -carpeted room, and the basement seems to have vanished.

Continuity mistake: At the end of 'The Shining, ' the family sits in the snow, Homer holding Willie's portable TV.

This is all due to the lack of correct colorization.
