Gomez Addams: [admiring Morticia, who is sleeping.] Look at her. I would die for her. I would kill for her. Either way, what bliss!
Question: It is revealed at the end of the film that Gordon is in fact the true Fester. However, all the photos and Gomez's home movie show young Fester as being completely bald. Then how did Gordon manage to have a full head of hair which he had to shave off in order to initially pose as Fester?
Answer: I guess we assume he always shaved his head.
Answer: Presumably when Fester was lost in the Bermuda Triangle, whatever supernatural forces caused him to lose his memory also made him grow hair. This gets reversed at the end of the movie when he's zapped by lightning, restoring his memories and destroying his hair follicles as well.
