A number of the characters had names that were alliterated. These were Todd Tomorrow, Francine Fishpaw, Cuddles Kovinsky, Sandra Sullivan and Bo-Bo Belsinger. One of the lead cast had an alliterated name too that being Ken King.
There was a scene that was cut during production where Dexter relapsed after returning from prison and shaved off an eyebrow. This explains why he has both eyebrows upon returning home and towards the end of the film.
