Other mistake: In the sequence where the security guard is hunting Buddy and Felix in the supermarket, there is a shot where the guard's legs aren't animated, making the model appear to float as he walks between them. (00:28:37)
Audio problem: Throughout the movie, different characters' voice lines vary in audio quality. Sometimes they are standard quality; other times they sound extremely compressed. These low-quality audio clips are often mixed with high-quality audio clips, too. (00:00:01 - 01:30:27)
