Alice Hunsiker was the sister of Todd Hunsiker, and the daughter of Douglas Hunsiker, a neighbor of the Rodman family. She is afraid of Caesar, considering him to be a wild ape. As a young girl Alice saw Caesar sneak into her shed to play with her toys, which made her father grab a wooden bat to assault Caesar and as a teenager, five years later, she witnessed Caesar attack her father after a confrontation with Charles Rodman.
Alice and her brother probably became infected with the ALZ-113 virus and died when their father contracted it.
- In one of the film's trailers Alice and young Caesar wave to each other while Caesar is at the window and Alice is near her yard, although this was not in the film. In fact, Alice is afraid of Caesar and sent her father to pulverize him early in the film.
