This was a serviceable enough cop story/thriller back in the late '80s that showed director Ridley Scott was on his toes. Actors Berenger, Scott, Bracco, and Orbach were all in fine form. The one that stood out most though was Andreas Katsulas as the villain. I think Ridley Scott consciously picked him for the role because he resembled in action a kind of vicious "Alien" on Earth and an ode to Scott's career-making masterpiece. It's too coincidental that a pair of hands/claws grab onto closing elevator/spaceship doors and force them back open during the climaxes of both films. After seeing this movie, I was left with the thought that director Scott was a little full of himself. It's a good thing he went on to make the special, seminal "GI Jane."
