The Giant Woman was one of the beings held captive by the facility. She is seen in her glass cube prison after Marty and Dana realize where they are. She is not shown during the purge. A closer look of her appears in the bonus features section of the DVD.
Appearance and CharacteristicsEdit
She is depicted as a normal human woman who is of extraordinary size, wearing nothing but white revealing clothing. She is shown hunched over in her cube looking as though she is trying to find a way out. She doesn't appear to be of any evil nature, but she might have been considered dangerous if encountered by a victim.
It is unknown what item in the cellar summons her, but going by the 1958 and 1999 movies she is based on, it might be a diamond necklace.
The Giant Woman is a clear reference to Attack of the 50 Foot Woman. Other movies featuring this genre are The Thirty Foot Bride of Candy Rock, Village of the Giants, Dude, Where's My Car, Attack of the Fifty Foot Cheerleader and Attack of the Fifty-Foot Centerfold, also an episode of Phineas and Ferb has the exact name and genre in this case their own "big" sister.
