In the film, there are two characters named "Winston" – one appears at the beginning and end of the film, the other is Fritz's girlfriend Winston Schwartz. Michael Barrier notes that Winston Schwartz (who appears prominently in "Fritz Bugs Out" and "Fritz the No-Good") never has a proper introduction in Bakshi's film, and interprets the naming of a separate character as Bakshi's attempt to reconcile this; however, the two characters look and sound nothing alike. Bakshi intended to end the film with Fritz's death, but Krantz objected to this ending, and Bakshi eventually changed it to the final ending.
