 As revealed on the DVDs commentary the directors and producer had  difficulty agreeing on the look of Glen. The director wanted to give  him his own look and style but the producer felt that he should have  features similar to Chucky because after all Glen is his son. As a  result Glen was given blue eyes, red hair, and freckles like Chucky.  Glens blue eyes and red hair however are a different shade than  Chuckys.
