Dr. Daniel Jackson (James Spader), a scholar of ancient hieroglyphics, signs on to help the Air Force (led by Kurt Russell) unlock the mystery of a stone archway that's really a portal to another universe. There, they encounter a culture of friendly primitives and some not-so-nice dog-headed beasties armed with lasers. The Ultimate Edition of this visually creative space adventure offers a remastered director's cut, audio commentary and a featurette.
