Trivia, insights & behind the scenes
Released the same summer as Alien; audiences chose correctly. Warner had just finished Time Bandits and needed rent money apparently.
Filmed on location at Hopi and Navajo reservations with actual tribal members in supporting roles — progressive for 1979, though the 'white savior' structure undermines it.
