Primate’s ending was radically rewritten right before shooting

When Paramount Pictures’ animal-attack horror movie Primate debuted at Austin’s annual Fantastic Fest in September, the public release was still four months away. Attendees didn’t just get an early look at the gleefully gory, consciously campy horror movie about a family’s pet chimp Ben contracting rabies and going on a murder spree. They also got some startling stories about how it came together, including details about a major rewrite just ahead of shooting.
